Key concepts
3 concepts
- 1
A wave's amplitude is the distance from the peaks to the middle of the wave, while the wavelength is the distance between crests.
- 2
Transverse waves oscillate perpendicular to the direction of travel, while longitudinal waves oscillate in the same direction as the wave is moving.
- 3
Constructive interference occurs when waves build on each other, while destructive interference occurs when waves cancel each other out.
