Question

The image shows the path of light travelling through a glass slab.What causes the ray of light to deviate from its original path?​

Answer 1

Answer:

Answer = d) change in density of medium

As there is a change in the medium , the wavelength and velocity of light changes which makes the light to deviate from its original path.

The speed of light is less in denser medium as compared to a rarer medium.

Answer 2

The ray of light deviates because of (d) change in the density of medium.

Explanation:

The image illustrates refraction phenomenon of light.

Refraction is a particle property of light which demonstrates deviation of light ray from its original path because of change in medium.

• When a ray of light travels from mediums with different densities, there is change in speed of light which is why it deviates form its original path.
• When light travels from rarer medium to denser medium, it's velocity decreases and it bends towards the normal.
• Normal is a perpendicular line drawn at the interface of two mediums.
• When light travels from denser medium to rarer medium, it's velocity increases and it bends away from normal.
• Here, the light is traveling from rarer medium to denser medium and it is bending towards the normal.
