Wavelength The distance between one point on a wave and another point exactly like it.
Frequency The number of wavelengths that pass a point in one second. Measured in hertz (Hz). FM Radio station frequencies.
Frequency As frequency increases, wavelength becomes shorter. This is an inverse relationship.
Amplitude This is the “height” of a wave.
Amplitude The greater the amplitude, the more energy a wave has. AM Radio stations.
Wave Speed Another name for speed is velocity. Units for speed are usually a distance/time (cars: miles per hour)
Wave Speed Speed = Frequency x Wavelength Or… V = f x λ
Wave Speed Example: A wave has a wavelength of 2 m and a frequency of 3.5 Hz. What is the speed? V = 3.5 Hz x 2 m
Wave Speed Hint: 1 Hz = 1/second So V = 3.5/s x 2 m V = 7 m/s
Wave Speed Example: A wave has a speed of 9.0 m/s and a wavelength of 3.0 m, what is the frequency?
Wave Properties. Amplitude The distance a wave vibrates from its rest position. The distance a wave vibrates from its rest position. The greater the amplitude,

Measurements of waves: Transverse waves: Compression waves: compressionrarefaction.
Amplitude The max. distance the particles move from the “rest position” to: The more energy a wave has → The greater its amplitude Crest or trough OR.
