sound p2 4

The top (highest point) of the wave.

• trough

• crest

• frequency

The distance between one crest and the next crest

Or the distance between one trough and the next trough.

• wavelength

• frequency

One complete vibration (crest + trough)

• cycle

• frequency

• wavelength

The bottom (lowest point) of the wave.

• cycle

• trough

• crest

the number of waves that pass a point in a certain amount of time.

Or number of complete cycles a wave makes in 1 second

• frequency

• wavelength

Sound waves are measured by

• oscilloscope

• telescope

sound waves carry different amounts of energy.

• true

• false

Wave is a disturbance that carries energy from point to another point.

• true

• false

 

The shorter the wavelength

• the more energy the wave has.

• more frequency

• both of them

Sound waves travel at the same speeds through matter

• true

• false
