- 1what are the two types of wave-transverse
-longitudinal - 2what do all waves transferenergy from one place to another
- 3what do the particles that make up a wave dothe particles that make up a wave oscillate(vibrate) about a fixed point. In doing so they pass energy on to the next particles which also oscillate and so on.The energy moves along but the matter remains
- 4what is the oscillations like in a transverse wavein a transverse wave e.g a water wave, the oscillations are perpendicular(at right angles)to the direction of energy transfer.
- 5how can this be demonstrated (transverse)this can be demonstrated by moving a rope or a slinky spring up and down vertically - the wave then moves horizontally
- 6what are the oscillations like in a longitudinal wavein a longitudinal wave e.g a sound wave, the oscillations are parallel to the direction of energy transfer
- 7how can this be demonstrated (longitudinal)this can be demonstrated by moving a slinky spring moving back and forward horizontally-the wave also moves horizontally
- 8list the 4 things that all waves have and what they are-frequency- the number of waves passing a fixed point per second, measured in hertz
-amplitude-the maximum displacement that any particle achieves from its undisturbed position in meters
-wavelength-the distance from one point on a wave to the equivalent point on the next wave in meters
-period-the time taken for one complete oscillation in seconds - 9when observing waves what is the amplitude and the period-amplitude is seen as the wave height
-the period is the time taken for one complete wave to pass a fixed point - 10what is aamplitudeamplitude indicates the amount of energy a wave is carrying-the more energy the higher the amplitude
- 11what is the speed of a wavethe speed of a wave is the speed at which the energy is transferred (or the wave moves)
- 12what is the speed of a wave the measure of and what is the equation for itit is a measure of how far the wave moves in one second and can be found with the wave equation :
wave speed=frequency *wavelength - 13RQ)write a method for identifying the sustainability of apparatus to measure the frequency, wavelength and speed of waves in a ripple tank1-time how long it takes one wave to travel the length of the tank. Use this to calculate wave speed using speed=distance/time
2-to find the frequency count the number of waves passing a fixed point in a second
3-estimate the wavelength by using a ruler to measure the peak to peak distance as the waves travel
4-use a stroboscope to make the same measurements and compare the results - 14when waves are transmitted from one medium to another what changestheir speed and therefore there wavelength changes e.g water waves travelling from deep to shallow water or sound travelling from air into water
- 15what doesn't changethe frequency does not change because the same number of waves is still being produced by the source per second
- 16why is the speed and the wavelength of a wave always directly proportionalbecause all waves obey the wave equation
-doubling the speed doubles the wavelength
-halving the speed halves the wavelength - 17—
