The effect on the image position as the object position is changed.

Question

A small coin is resting at the bottom of a swimming pool. Draw a ray diagram of the situation, showing at least two incident rays (one on each side of the normal) and their refracted rays at the water-air interface. Trace the refracted rays back into the water until they converge. Now you can identify some right triangles that will allow you to deduce the apparent distance below the water of the coin in terms of its actual distance and the index of refraction. Derive from this the formula for the apparent distance.

Derive the optical law of reflection. Hint: Let light go from the point A = (x1, Y1) to B = (x2, Y2) via an arbitrary point P = (x, 0) on a mirror along the x axis. Set dt/dx = (n/c)dD/dx = 0, where D = distance APB, and show that then 0 = 4. 1. B

A laser (in red) hits the surface of a pool, is refracted at the interface and hits the bottom of the pool as shown on the drawing. The index of refraction of water is 1.33. The distances shown on the drawing are the following: L = 2.2 meters, H = 1 meters and D = 2.9 meters. What is the distance x? Express your answer in meters and keep three significant digits.
