The sun is 60° above the horizon. rays from the sun strike the still surface of a pond and cast a shadow of a stick that is stuck in the sandy bottom of the pond. if the stick is 19 cm tall, how long is the shadow?

shadow length 7.67 cm

Explanation:

given data:

refractive index of water is 1.33

by snell's law we have

solving for

from shadow- stick traingle

s = 19tan22 = 7.67 cm

s = shadow length
