types of waves

Transverse = Transverse waves are waves that travel perpendicular to the waves themselves

longitudinal = longitudinal waves are waves that travel parallel to the waves themselves

Definitions

Frequency = the number of complete waves per second

Wavelength = the distance from peak to peak or trough to trough

Rarefaction = a point at which waves are further away from each other than normal

Compression = a point at which waves are closer together than normal

Amplitude = the distance from the horizontal axis to the peak

Critical Angle = the angle of incidence at which the angle of refraction is 90

Focal length = The distance between the center of a lens and the principal focus

Diffraction = waves spreading out when it goes through a small gap
