As light shines from air to water (n = 1.33) at an incident angle of 45.0°, what is its angle of refraction? r = ° 0.500 1.60 148 32.1

The correct answer of this question is :

EXPLANATION :

As per the question, the light is moving from air to water.

The angle of incidence is given as i = 45 degree.

The refractive index of water with respect to air is given as n = 1.33.

We are asked to calculate the angle of refraction.

From Snell's law, we know that -

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
