Key characteristics of waves

Wavelength

Node

Amplitude

Antinode

Amplitude: The height of the wave from node to antinode (transverse waves), or the distance between compression and rarefaction in a in a compressive wave. Measured in units describing the wave

Antinode: The extreme point of the wave (max or min amplitude)

Wavelength: The distance traversed by a full cycle of the wave Node: The “zero point” of the wave

Frequency: The rate of occurrence of the wave (in Hertz or cycles / second)

Period: The time between successive waves

Speed of Waves

where v is the speed, f is the frequency, and lambda is the wavelength.

Example of what happens when you change the speed!

v = f

The relationship between wave speed, wavelength, and frequency is simple

•For a given temperature, pressure, material, etc.

Doppler Effect: When the source of sound (or the hearer of the sound) is moving, the waves in front of the source “bunch up” and the waves behind the source spread out. The frequency goes up in front and gets lower behind the source as it goes by.
