Acatfish is spotted at the bottom of a creek. the depth of the water is 2 m. a hunter (with no knowledge of optics) fires a rifle shot, directly aimed at the catfish. the bullet strikes the water at an angle of 40° to the water. assume that the bullet is not deflected by the air/water interface, what is the distance from the bullet hole at the bottom of the creek to the catfish? water: n=1.33. (answer should be 0.97 m)

Explanation:

Given:

Apparent distance from the normal projection at the bottom of entrance at air-water surface to the fish:

Now according to Snell's Law:

Now the actual distance of the fish from the bottom surface at the normal:

Now distance between bullet hole and fish:

where are the vectors ?

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
