What will most likely happen if a light wave moves through a solid?
2 answers:
<u>Answer:</u> the correct answer is it will decrease in speed.
<u>Explanation:</u>
There are 2 types of waves:
1. Longitudinal waves: These waves are the waves where the particles of the medium propagates in the direction of the wave. These waves requires a medium to travel. For Example: Sound Waves.
2. Transverse wave: These waves are the waves where the particles of the medium propagates perpendicular to the direction of the wave. These waves does not require a medium to travel. They can travel in vacuum also. For Example: Light waves.
Speed of light wave is constant in the vacuum which is but its speed decreases as it enters a medium. And, here the light is entering a solid having certain refractive index, so the speed would decrease.
Hence, the correct answer is it will decrease in speed.

Answer:
1408.685 KN/C
Explanation:
Given:
R = 0.45 m
σ = 175 μC/m²
P is located a distance a = 0.75 m
k = 8.99*10^9
- The Electric Field Strength E of a uniformly solid disk of charge at distance a perpendicular to disk is given by:
part a)
Electric Field strength at point P: a = 0.75 m
part b)
Since, R >> a, we can approximate a / R = 0 ,
Hence, E simplified relation becomes:
E = σ / 2*e_o
part c)
Since, a >> R, we can approximate. that the uniform disc of charge becomes a single point charge:
Electric Field strength due to point charge is:
E = k*δ*pi*R^2 / a^2
Since, R << a, Surface area = δ*pi
Hence,
E = (k*δ*pi/a^2)
