To cross the river a swimmer chooses the direction minimizing the amount of time spent in the water. The swimmer swims at a cons
tant speed of 2.00 m/s. The river is flowing uniformly between the parallel banks 73.0 m apart at a constant flow speed of 8.00 m/s. Find the distance (in meters) downstream from the starting point where the swimmer will reach the opposite shore of the river.
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. The wavelength decreases as the light enters the medium and the light wave changes direction.
