Wave
What is a wave?
A wave is a disturbance that transfers energy from one place to another.
What is a medium?
A medium is the material through which a wave travels.
Is the material through which a wave travels.
Medium
What is a longitudinal wave
In a longitudinal wave ,particles move back and forth in the same direction that the wave travels or parallel to the wave
Particles move back and forth in the same direction that the wave travels or parallel to the wave
Longitudinal wave
What is a transverse wave
