Question

When travelling obliquely from one medium to another medium, the direction of propagation of light in the second medium?

• A. remains same
• B. changes
• C. may change or remain same
• D. none of these

Answer 1

The correct option is B

changes

When the light ray travels from one medium to another medium at an angle, it undergoes refraction. In refraction, the light bends according to the density of the medium. If the density of the second medium is more than the first, light bends towards the normal and if the density of the second medium is less than the first, light bends away from the normal. Due to this, the bottom of a tank or a pond containing water appears to be raised.
