Question

37. Refractive Index of the medium A relative to medium B is *​

Answer 1

Answer:

√6 / 3

Explanation:

Using snell's law,

n = sin i / sin r

n = sin 45° / sin 60°

we know that,

sin 45° = 1 / √2 and sin 60° = √3 / 2

∴ Using these values,

we get,

n = 1 / √2 ÷ √3 / 2 = √2 / √3

rationalising the denominator,

n = (√2 × √3) / (√3 × √3) = √6 / 3

∴ the refractive index is √6 / 3
