Aperson is standing on the steps at the shallow end of the pool. what wave property explains why his/her feet appear closer to the surface then they really are? reflection interference diffraction refraction

Diffraction

Explanation:

When light enters water at an angle, it is bent downward by diffraction. However, our brain sees the underwater image as if it were on a straight line.

Thus, the bottom of the pool appears to be shallower than it actually is.

A is wrong. If all the light were reflected from the surface, we wouldn't be able to see the person's feet.

B is wrong. if all the light rays interfered with each other, we wouldn't be able to see anything.

D is wrong. Refraction is the bending of light as it passes the edge of an object.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
