A ray of light traveling in air strikes a flat 2.00 cm thick block of glass (n = 1.50) at an angle of 19.0 ◦ with the normal.?
a) Trace the light ray through the glass, and find the angle of refraction for light passing from air to glass. Answer in units of ◦.
b) Find the angle of refraction for light passing from glass to air. Answer in units of ◦.
Answer:
(a). [tex]\theta_2 = 12.5^o[/tex]
(b). [tex]\theta_1 = 19.0^o[/tex]
Explanation:
(a).
Snell's law says
[tex]n_1sin(\theta_1) = n_2sin(\theta_2)[/tex]
which in our case gives
[tex](1.00)sin(19.0^o) = (1.50)sin(\theta_2)[/tex]
Solving for [tex]\theta_2[/tex] gives
[tex]\dfrac{(1.00)sin(19.0^o)}{1.50} = sin(\theta_2)[/tex]
[tex]\theta_2 = sin^{-1}[\dfrac{(1.00)sin(19.0^o)}{1.50}][/tex]
[tex]\boxed{\theta_2 = 12.5^o}[/tex]
which is the angle of refraction from air to glass.
(b).
When the light ray goes from glass to back to air again, the angle of refraction equals the angle with which it had entered the glass because of the symmetry in Snell's law:
[tex](1.00)sin(\theta_1) = (1.50)sin(12.5^o)[/tex]
[tex]\boxed{\theta_1 = 19.0^o}[/tex]
The result is that the outgoing ray (one that refracted out from glass to air) and the tracing of the incoming ray (one that refracted into the glass) are parallel to each other.
How would a small bar magnet be oriented when placed at position X
Answer:
D
Explanation:
Well opposites attract, don't they?
A bar magnet at position X will align according to external magnetic fields, typically aligning its north pole towards the geographic North Pole. When experimenting with two magnets, opposite poles attract while like poles repel, which can be visualized with iron filings arranging along a magnetic field.
When a small bar magnet is placed at position X, its orientation will be determined by the external magnetic fields present. If there is no significant external field other than the Earth's magnetic field, a freely suspended bar magnet would align with the Earth's magnetic field lines, where one pole (north-seeking) faces the geographic North Pole and the south-seeking pole faces the geographic South Pole.
However, if we follow instructions similar to those given—placing one bar magnet on the table and bringing the north end of another bar magnet close to the south end of the first, we expect to see attraction between the opposite poles. Conversely, if two like poles are brought close together, they will repel each other. These interactions are due to the magnetic field lines that emerge from the north pole of a magnet and enter at the south pole.
Bar Magnet and Magnetic Field Lines: Utilizing iron filings around bar magnets can visualize these lines. The filings align with the magnetic field, showing the typical dipole pattern. When two bar magnets are placed with the same poles facing each other, the filings will show a pattern indicating repulsion, with field lines diverging. In contrast, when opposite poles are near each other, filings will align to show attraction, with field lines converging.
When a 5 kilogram mass is
raised vertically
2 meters from the ground, what is its gain in potential energy?
Answer:If a 5-kilogram mass is raised vertically 2 meters from the surface of the Earth, its gain in potential energy is approximately 1) 0 J 2) 10 J 3) 20 J 4) 100 J 43.
Explanation:
The gain of potential energy of the object is 980 joule.
What is potential energy?Potential energy is the energy held by an object as a result of its position relative to other objects, internal stresses, electric charge, or other factors.
The gravitational potential energy of an object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field are all examples of common types of potential energy. The joule, denoted by the symbol J, is the unit of energy in the International System of Units (SI).
Mass of the object: M = 5 kilogram
Vertical distance raised: h = 2 meter.
Acceleration of the gravity: g = 9.8 m/s ².
Hence, its gain in potential energy = Mgh
= 5 kilogram × 2 meter × 9.8 m/s²
= 980 Joule.

Will there be noise cancellation in example A or
example B?
Answer:
b
Explanation:
Yes, there is a noise cancellation in example B.
What is noise cancellation?
Active noise control, also known as noise cancellation or active noise reduction, is a method of reducing unwanted sound by adding a second sound designed specifically to cancel the first.
Active noise cancellation employs more advanced technology to actively combat noise. Essentially, it detects and analyzes the sound pattern of incoming noise before producing a mirror "anti-noise" signal to cancel it out. As a result, you hear a significantly reduced level of noise.
As we understood that the unwanted noise is cancelled by the second sound wave which reduces or cancels the unwanted sound wave. Example B is showing that the other wave is cancelling the noise and making the sound more noise free.

Roshan makes the table below to describe how to draw a ray diagram for a convex lens.
What error did Roshan make?
The ray that goes through the center should bend and go through the focal point on the other side.
The ray that starts out parallel with the main axis should bend toward the axis and go through the focal point on the other side.
The ray that goes parallel to the main axis after passing through the lens should also be parallel from the object to the lens.
The rays in the table describe how rays are drawn for a concave lens rather than for a convex lens.
The error that Roshan made is: the rays in the table describe how rays are drawn for a concave lens rather than for a convex lens.
What is lens?A lens is an optical device that is used to focus or diverge light rays through refraction. It is made up of a transparent material, such as glass or plastic, with at least one curved surface.
Roshan's table contained an error because he described the ray diagram for a concave lens rather than a convex lens.
A concave lens's ray diagram differs from that of a convex lens because the concave lens diverges light while the convex lens converges light.
After passing through the lens, the ray should be parallel to the main axis from the object to the lens. This is due to the law of refraction, which states that the incident angle equals the refracted angle.
Thus, Roshan's error was describing the ray diagram for a concave lens rather than a convex lens.

Roshan's error was in stating that a ray passing through the center of a convex lens should bend and go through the focal point on the other side, which is incorrect as such rays do not change direction.
Roshan's error in describing how to draw a ray diagram for a convex lens is in the statement that 'The ray that goes through the center should bend and go through the focal point on the other side.' In fact, rays that pass through the center of a convex (converging) lens continue in a straight line without bending. The correct rules are:
A ray entering a converging lens parallel to its axis passes through the focal point F of the lens on the other side.A ray passing through the center of either a converging or a diverging lens does not change direction.Therefore, the correct statements for a convex lens would be that a ray that starts out parallel with the main axis should bend toward the axis and go through the focal point on the other side, and that the ray passing through the center of the lens should not deviate from its path.

How can you tell the difference between chemical sedimentary rocks and intrusive
igneous rocks?
Answer:
Sedimentary rocks are usually formed under water when grains of broken rocks are glued together while igneous rocks form when melted rock (magma or lava) cools and metamorphic are rocks that once were igneous or sedimentary rocks but have been changed by pressure and temperature.
Igneous rock is formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks are formed from the products of weathering by cementation or precipitation on the Earth's surface. Metamorphic rocks are formed by temperature and pressure changes inside the Earth.

Experimental results have been presented showing that when an elastically soft material slides on a smooth surface, the coefficient of sliding friction increases with speed over a wide range of sliding velocities.
Slip friction is defined as the force acting between moving surfaces. An object moving on the surface receives a force opposite to its direction of motion. The magnitude of the force depends on the coefficient of dynamic friction between the two materials.
Is dynamic friction the same as frictional force?Even if two surfaces pass each other, there may be frictional force between the surfaces, and this sliding friction is called dynamic friction.
