Explanation:

Speed of the light waves changes as the medium changes

Answer 2

Although your question is incomplete, you may be referring to this question:

Which statement best describes the property of light waves illustrated in the diagram below?

(a) some materials absorb light waves.

(b) Some materials are refracted by some materials.

(c) Light waves are refracted by some materials

(d) Light waves are emitted by some materials ​

The best statement that describes the property of light waves illustrated in the diagram below is Light waves are refracted by some materials. (option c)

What is refraction?

• The property of bending of light when it passes from one medium to another is called refraction.

• It occurs because light travels at different speeds in different media.

• This difference in speed is due to the compression of wavefront when light passes from a rarer to a denser medium.

• Refraction is governed by Snell's Law, which states that:

                                    μ₁ sini = μ₂ sinr

where μ₁ and μ₂ are the refractive indices of medium1 and medium 2 respectively

         i is the angle of incidence

 and r is the angle of refraction

What does the given figure represent?

• In the given figure, we can see that a pencil is dipped into a beaker of water.

• Since light is traveling from air to water, its speed will slow down. This leads to the pencil appearing raised.

• This is so because the bent light rays converge above the real depth, so the image is formed at the apparent depth.

• The apparent depth is given by:

                       $d_{app}$ = $\frac{d_{real} }{refractive index}$

Thus the correct option is (c) Light waves are refracted by some materials.
