In the figure below, a ray of light A incident from air suffers partial reflection and refraction at the boundary of water.

(a) Complete the diagram showing (i) the reflected ray B and (ii) the refracted ray C.

(b) How are the angles of incidence i and refraction r related?

Solution:

The angle of incidence and refraction are connected according to Snell’s law.

μ_w = sin i / sin r

i
