Question

8. Consider four mediums P, Q, R and S whose refractive
indices are 2.14, 1.99, 2.98, and 2.16 respectively.
Assume that if light travels from one medium to
another. The rate of change will be utmost in which
medium,
(a) P to Q
(b) Q to R
(c) R to s
(d) S to P​

Explanation:

answer:

R to Q

Answer 2

The rate of change will be utmost in which (b) Q to R medium.

• When a ray of light travels from a medium with a lower refractive index to a medium with a higher refractive index, then the ray of light will bend towards the normal.
• While the ray of light will bend away from the normal while traversing from a medium with a higher to lower refractive index.
• The higher the difference in the refractive indices of the media, the higher will be the bending.
• So, the maximum bending will occur while light travels from a medium with refractive index 1.99 and 2.98. The medium with these refractive indices is Q and R respectively.
