G4 T3 Waves and informations L2 March 22

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.

Pattern of Waves

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.

Patterns of waves Notebook

• Oscillate

• circular waves

• Plane wave
