What happens to the direction and speed of the wave when it gets reflected

2
can anyone answer pls
its direction is confined to the same straight line in the oposite directon and makes an angle with the normal such that angle of incidence=angle of replection.there is no change in the speed of the wave.thank you.it was fun....

When a light wave is reflected,direction may alter based on angle of incidence.But speed never changes in reflection.There is a chance for speed change in refraction.

Simply direction of wave depends on angle of incidence and speed does not changeĀ
