Question

QUESTION 15:
If a ray of light takes t1 and t2 times in two media of absolute refractive indices u1and u2 respectively to
travel same distance, then​

Answer 1

Given that,

If a ray of light takes t₁ and t₂ times in two media of absolute refractive indices u₁ and u₂ respectively.

We know that,

When a light ray travel one medium to another medium then the direction of light is change it is called refraction.

This phenomena can be explained by the snell's law.

The snell's law is,

$u_{1}\sin i=u_{2}\sin r$

Where, u₁ and u₂ shows the refractive indices.

Hence, This is required answer.
