Question

the refraction of light is commonly a topic of study in physics and physical science courses. however, humans encounter this phenomenon more often than they realize. for example, warning signs around a community pool warn of deep waters near the deep end of 6 feet. in what manner is light refraction playing a role at the community pool? a light bending around the ripples in the pool distort the clarity of the water, making it less safe for users. b light bouncing from the water surface back to the eyes of a pool user may cause a momentary blindness if the light is too intense c the water in the deep end appears shallower than it really is because light traveling from the bottom bends when it reaches the surface. d light interacting with the chlorine in the water can cause the water to appear discolored, making it difficult to judge the depth of the water.

Explanation:

Refraction is the bending of light as it passes from one medium to another. In the case of a pool, light travels from water (a denser medium) to air (a rarer medium). When light rays from the bottom of the pool reach the water - air interface, they bend away from the normal. This makes the bottom of the pool, especially the deep - end, appear shallower than it actually is.

Answer:

C. The water in the deep end appears shallower than it really is because light traveling from the bottom bends when it reaches the surface.
