1. 11-2: Wave Properties

2. 1. Parts of a Transverse Wave
Crest – highest points of the wave
Trough – lowest points of the wave

3. 2. Parts of a Compressional Wave
Compression – region where medium is crowded together and more dense
Rarefaction – less dense area of the wave

4. 3. Wavelength
Distance between one point on a wave and the nearest point just like it
Transverse – crest to crest or trough to trough
Compressional – compression to compression or rarefaction to rarefaction

5. 4. Frequency Measured in hertz (Hz)
Transverse – count the number of crests or troughs that pass by a fixed point each second
Compressional – number of compressions or rarefactions that pass a fixed point every second

6. 5. Wave Speed
Dependent on the medium through which the wave is traveling
Example: light travels faster than sound
Measured in meters per second (m/s)

7. 6. Amplitude
The greater the amplitude the more energy that is carried and vice versa
Transverse – distance from resting point to crest or trough
Compressional – denser the compressions the greater the amplitude (text pg 336)
