Sound Waves - Wavelength and Amplitude
Karten in diesem Stapel (8)
- 1The wavelength of a wave is the distance over which the wave's shape repeats itselfIt is represented by the symbol λ
- 2An example of this is shown with the sine wave
- 3The top of the wave is called the crest and the bottom is called the troughThe wavelength can be measured from crest to crest or from trough to trough
- 4The SI unit of wavelength is the meter.This is same for all types of waves
- 5We can find the wavelength of a sound wave from the equation λ =\(\frac{v}{f}\)Where λ is the wavelength,
v is the speed of sound and
f is the frequency - 6The amplitude of a wave is the change over a periodPeak-to-peak amplitude is measured from the trough to the crest of the wave
- 7The amplitude effects the loudness of the tone of the soundThe bigger the amplitude, the louder the sound
- 8The amplitude is not always constant with sound wavesIt can vary with time / position
