A fish swims 4.0 m below the surface of a still lake as shown in the figure.When an archer attempts to shoot the fish,the arrow enters the water at point P that is a horizontal distance 1.2 m from the fish.

-If the archer is successful in shooting the fish,what angle does the arrow make with the horizontal as it enters the water?
A)12°
B)17°
C)23°
D)67°
E)73°

The arrow makes an angle with the horizontal equal to the angle of refraction as it enters the water. According to Snell's law, the angle of refraction is determined by the indices of refraction of the two media (air and water) and the angle of incidence. However, without specific values for the angle of incidence or the indices of refraction, we cannot directly apply Snell's law. The question seems to lack sufficient information for a detailed calculation based on physics principles. However, if we assume the question implies a scenario where the angle is being asked in a general sense, and without additional context, we cannot accurately calculate it. Given the choices, without specific context or calculations provided in the question, the correct answer cannot be determined through physics principles alone. Thus, my response is based on the assumption that there might be a specific context or a common understanding related to the scenario not provided in the question.
