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.

the correct answer is it will decrease in speed.

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 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.

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders
