It's nighttime, and you've dropped your goggles into a 2.8-m-deep swimming pool. If you hold a laser pointer 1.0 m above the edge of the pool, you can illuminate the goggles if the laser beam enters the water 2.2 m from the edge.
How far are the goggles from the edge of the pool?

It’s nighttime, and you’ve dropped your goggles into a swimming pool that is 4.0 m deep. If you hold a laser pointer 1.5 m directly above the edge of the pool, you can illuminate the goggles if the laser beam enters the water 2.1 m from the edge. How far are the goggles from the edge of the pool? I don't understand this problem, can someone help break it down for me to understand it step by step? Thanks

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.
A flashlight is held at the edge of a swimming pool at a height h = 2.2 m
A flashlight is held at the edge of a swimming pool at a height h = 2.2 m such that its beam makes an angle of θ = 58 degrees with respect to the water's surface. The pool is d = 1.5 m deep and the index of refraction for air and water are n1=1 and n2 = 1.33, respectively. What is the horizontal distance D, from the edge of the pool to the port on the bottom of the pool...

You are standing at the edge fo a swimming pool and shining a laser pointer onto the water surface. The laser beam hits the water at an angle of 50.8 deg above the horizontal. Some of the lights reflects off the water surface, and some enter the water. Find the angle between the reflected and refracted rays. From Snell's law I got the refracted angle of the laser beam= 35.64 deg. Then I thought it was just the difference between...

You put a mirror at the bottom of a 1.8-m-deep pool. A laser beam enters the water at 26° relative to the normal, hits the mirror, reflects, and comes back out of the water. Part A How far from the water entry point will the beam come out of the water? Express your answer with the appropriate units.
