An incident ray of light strikes water at an angle of 30°. the index of refraction of air is 1.0003, and the index of refraction of water is 1.33. what is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°

The angle of refraction is 22°.

Explanation:

To calculate the angle of refraction, we use the formula given by Snell's Law:

where,

= refractive index of the faster medium, where refractive index is smaller = 1.0003

= refractive index of the slower medium, where refractive index is greater = 1.33

= angle of incidence = 30°

= angle of refraction = ?

Putting values in above equation, we get:

Hence, the angle of refraction is 22°.
