Question

A summer is tredaing in water (whit her head above the water) at the sarface of the bool 3 mater deep she sees a coin on the bottom directly below . How deep does the coin appear to be

Answer 1

The coin will appear to be less deep than it actually is due to the refraction of light in the water. The apparent depth of the coin will be shallower than its actual depth, so it will not appear to be 3 meters deep. The exact depth it appears to be will depend on the angle at which the summer is looking at the coin and the refractive index of the water.
