Refraction causes waves to change direction at media boundaries without energy loss.
Refraction is the change in direction of a wave due to a change in its medium density. It occurs at the boundary between two media, causing the wave to bend and change its speed and wavelength.
When two waves interfere, there is no loss of energy in the system. Energy is conserved, and the interference can lead to either constructive or destructive interference, where energy is redistributed but not lost.
When light passes from air to water, for example, refraction occurs at the boundary, resulting in the bending of light due to the change in density of the media.
