How different is the propagation of light from the flow of water?

1.	How different is the propagation of light from the flow of water?
Answer» tion of waves has both a speed and a DIRECTION, called the velocity. The velocity of light changes depends on the MATERIAL it travels through. Light waves can be changed in a few different ways. Reflection is when the waves BOUNCE off a surface and CHANGE direction, like when they hit a mirror or POOL of water
