Question

If the refractive index of
water with respect to air
is 4/3.Calculate the refractive
index of air with respect to
water ​

Answer 1

Answer:

R.I = 3/4

Explanation:

R.I of air with respect to water = 1 / (4/3) = 3/4

Answer 2

Answer:

0.75

Explanation:

Refractive index of water w.r.t air =

n/1

n/2

=

3/4

and refractive index of air w.r.t water =

n /2

n /1

=

4/3

=0.75
