Question

A scuba diver sees light reflected from the water’s surface. At what angle relative to the water’s surface will this light be completely polarized?

answer to 3 decimal places

Answer 1

Answer:-

(note- external source like internet help is taken to get the exact values )

it is given that the refracting medium is water,

we can find the refractive index refracting medium , thus we have

$n_2=1.333$

and $n_1 (air)=1.000293$

and we know that

$tan(\theta)=\frac{n_2}{n_1}\\ \theta=tan^{-1}(\frac{n_2}{n_1})$

putting the values we get

$\theta=tan^{-1}(\frac{1.33}{1.000293})\\ \approx\boxed{53.115^o} \ answer$
