Waves
Cards in this deck (15)
- 1What is the peak/crest?The highest point in the wave
- 2What is the trough?The lowest point in the wave
- 3What is the amplitude?The length between the peak/crest and the rest position / The length between the trough and the rest position
- 4What is the wavelength?A point on the wave to the same point on the next wave
- 5What is the wavelength symbol and what is it measured in?λ (lambda)
cm & m - 6What is the frequency and what is it measured in?The number of waves that pass a point each second and is measured in Hz (Hertz)
- 7What types of waves are there?Transverse & Longitudinal
- 8What is a transverse wave?Waves where the vibrations (oscillations) are at right angles to the direction of the wave's energy
- 9What is a longitudinal wave?Waves where the vibrations (oscillations) are parallel to the direction of the waves energy
- 10What is the wavespeed equation?Wave speed (m/s) = Frequency (Hz) x Wavelength (m)
- 11What is the abbreviation of the wavespeed equation?v = Fλ
- 12A wave of wavelength 3m is travelling with a frequency of 5hz. Calculate it's speed.v = fλ
= 5 x 3
= 15 m/s - 13A wave is travelling at 12 m/s. It has a frequency of 4hz. Calculate it's wavelength.v = fλ
λ = v/f
λ = 12 m/s / 4hz
λ = 3m - 14What is the time period of a wave and what is it measured in?The time taken for one wave to occur and is measured in seconds
- 15How can it be calculated?By finding the reciprocal of the frequency (f = 1/T and T = 1/f)
