A man is fishing from a dock using a laser gun to see beneath the water. Should he aim:

A. Somewhat above the fish.
B. Directly at the fish.
C. Somewhat below the fish.
D. Somewhat at the side of the fish.

Answer :

Final answer:

The man should aim somewhat above the fish due to the phenomenon of refraction, where light changes direction when entering water from air. This can also be applied to a boat traversing a river, where it may need to aim 'upstream' to reach a specific point.Thus, the correct answer is option A

Explanation:

This question is addressing the phenomena of refraction, which is a part of Physics. When light, in this case the laser from the gun, enters water from air, it slows down causing it to change direction. This is known as the refraction of light. If you consider this, the man should aim somewhat above the fish, not directly at it.

Let's apply this to a real-life scenario of a boat moving in a river. Assuming the boat is maintaining an angle of 18.4° to a line drawn across the river and a resultant velocity of 15.8 m/s. Given these factors, to reach a certain point across the river, the boat might have to point somewhat 'above', or upstream from the direct crossing point, as the current may try to push it 'downstream'.
