Changing wave motion Flashcards
1
Q
what is refraction
A
refraction is when a wave crosses to a new medium at an angle ( not 90 degrees ). the change in the waves speed will cause the direction of the wave to change making the wave appear to bend
2
Q
what is reflection
A
reflection happens when a wave hits a flat surface and bounces off
3
Q

A
