Question

What is the critical angle for water air media​

Answer 1

$\huge\underline\green{Answer:-}$

So the critical angle is defined as the angle of incidence that provides an angle of refraction of 90-degrees. Make particular note that the critical angle is an angle of incidence value. For the water-air boundary, the critical angle is 48.6-degrees.

Answer 2

Explanation:

the critical angle is

${ \boxed{ \red{48.6-degrees}}}$
