Question

What will most likely happen if a light wave moves through a solid?

It will increase in wavelength.
It will decrease in speed.
It will increase in speed.
It will decrease in wavelength.

Answer 1

in will most likely decrease its speed.
hope this helps.

Answer 2

Answer: the correct answer is it will decrease in speed.

Step-by-step explanation:

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
`3* 10^8m/s` 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.
