Cards in this deck (12)
- 1State an example of a transverse wave.Light
- 2State an example of a longitudinal wave.Sound
- 3Waves can be either _____________ or ______________.Transverse or Longitudinal
- 4In transverse waves, _________________________________________.The oscillations are perpendicular to the direction of energy transfer.
- 5Longitudinal waves ________________________________________.Show areas of compression and rarefaction. The oscillations are parallel to the direction of energy transfer.
- 6What is the difference between a transverse and longitudinal wave?In transverse waves the oscillations are perpendicular to the direction of energy transfer and parallel in longitudinal waves.
- 7What is the amplitude of a wave?The maximum displacement of a point on
a wave away from its undisturbed position. - 8What is the wavelength?The distance from a point on one wave
to the equivalent point on the adjacent wave. - 9What is the frequency of a wave?The number of waves passing a point
each second. - 10What is the equation for period?period = 1/frequency
t = 1/f
period, T, in seconds, s
frequency, f, in hertz, Hz - 11What is wave speed?The speed at which the energy is transferred (or the wave moves) through the medium.
- 12What is the equation for wave speed?wave speed = frequency × wavelength
v = f λ (lambda)
wave speed, v, in meters per second, m/s
frequency, f, in hertz, Hz
wavelength, λ, in meters, m
