Question

If you were to stand on the edge of a pond and spear a fish in the pond, would you aim above, below, or directly at the fish you see to make a direct hit? Take your time and draw a clear diagram of the light rays involved. Include a brief explanation. If you were to stand on the edge of a pond and zap a fish in the pond with a laser, would you aim above, below, or right at the fish you see to make a direct hit? Take your tune and draw a clear diagram of the light rays involved. Include a brief explanation. If a fish were to look toward the surface of the water at a 45 degree angle, would it see the sky or the bottom of the pond? Water has an index of refraction, n_water = 1.329, and air has an index of refraction, n_air = 1.

Explanation / Answer

problem 2

nwater = 1.329

nair = 1

i = angle of incidence = 45

r = angle of refraction

using snell's law

nwater Sini = nair Sinr

1.329 Sin45 = 1 Sin r

r = 70.1

hence fish see the sky
