Do Now
1- A wave that moves in all directions is ( circular wave/ plane wave).
2- The amount of time it takes a wave to complete one back and forth is ( wavelength/wave period)
3- The distance between two crests is (amplitude/wavelength/trough)
4- Define Plane wave.

5
Waves can combine
When more than wave moves through a medium, they can meet.
When this happens, the waves add together as they travel through each other.
This is called Superposition
6
Superposition
Waves meeting and combining as they move.
When the crests of two waves meet, their two amplitudes add together.(the wave is taller for a moment)
Thats how waves can move through each other.
