Question

3. The minimum value of refractive index of the medium is unity. Explain why?

Answer 1

Answer:

your answer is a answer where I am writing your answer where that is the answer.

I guess

Answer 2

Refractive index

= speed of light in vacuum /

speed of light in medium.

Or ,

n = c / v

The max value if v will be 3 × 10^8 or in other words v= c.

So , n= c/v

n = c/c

n = 1.

Hope u understood
