PLLLZZZZ HELPPPP!!!
Will a pool appear to be shallow if viewed at a 90 degree angle??
​

Answer 1

Answer:

Real and apparent depth. The refraction of light at the surface of water makes ponds and swimming pools appear shallower than they really are. ... When light emerges from glass or water into air it speeds up again. If it meets the glass-air boundary at any angle other than 0o it will refract away from the normal.
