Question

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

Answer 1

Propagation 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
