Homework Statement
At a marine animal park, Alison is looking through a glass window and watching dolphins swim underwater. If the dolphin is swimming directly toward her at 15 m/s, how fast does the dolphin appear to be moving?
Homework Equations
v=15 m/s
I realize that due to the refraction of light coming off of the dolphin, the dolphin appears to be swimming slower than it actually is.
I am supposed to use the concept of the the refraction of light: Snell's Law, but I'm not really seeing how to approach the problem here.
