Flashcards
Waves - Wave Properties
Cards in this deck (8)
- 1Waves have many different propertiesThese include the wavelength, the frequency, the amplitude and the period
- 2The frequency of a wave is the number of cycles per unit timeIt is measured in Hertz - Hz.
1 Hz means that an event repeats once per second - 3The frequency of a wave is inversely proportional to its period, T =\(\frac{1}{f}\)The period of a wave is the duration of one cycle of that wave and is measured in seconds
- 4The wavelength of a wave is the distance over which the wave's shape repeats itself, and has the symbol λ
- 5The 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, and is measured in meters
- 6We can relate all of these properties using the equation λ =\(\frac{v}{f}\)Where λ is the wavelength,
v is the speed of sound and
f is the frequency - 7The amplitude of a wave is the change over a periodPeak-to-peak amplitude is measured from the trough to the crest of the wave
- 8Generally in questions, you will not use the peak-to-peak amplitudeYou will take the amplitude to be the height from the x-axis to the crest of the wave
