You’re standing in waist-deep water with your eyes 0.46 m m above the surface. A fish is swimming 0.65 m below the surface. Your line of sight to the fish makes a 38 ∘ angle with the water’s surface.
How far (horizontally) from you is the fish?
Express your answer to two significant figures and include the appropriate units.
Homework Answers
Angle of incidence i = 90 - 38 = 52 degree
angle of reflection r = arcsin ((sin i)/n) = arcsin ((sin 52 degree)/1.33) = 36.33 degree
Horizontal Distance = 0.46*tan 52 degree + 0.65 tan 36.33 degree
= 1.1 m answer

You are standing in a 1.5-m-deep swimming pool at night. The water is very still. You hold a laser pointer just above the water's surface and shine it nearly parallel to the surface, but tilted slightly down so that the beam enters the water 3.5mfrom you. How far from you does the beam strike the bottom of the pool? Index of refraction of the water is 1.33.

Suppose that your eyes are 1.70 m above the ground. While at a
large lake, you think of a relatively-easy way to calculate the
radius of the Earth. By standing on the shore and communicating
with someone in an approaching boat, and using the GPS locators in
your phones, you determine that you can just see the boat above the
horizon when it is at a distance of 4.65 km. That is, your line-
of-sight distance to the horizon is...

In winter a lake has a 0.35 m thick ice layer over 1.10 m of water. A light beam from above strikes a spot on the ice, making a 34 ∘ angle with the normal. Part A How far horizontally from that spot does the light ray strike the lake bottom? Express your answer to two significant figures and include the appropriate units.
