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.

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

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.
