Fichas del conjunto (18)
- 1What is a progressive wave?A transfer of energy through matter. No matter is transferred with it, it just vibrates.
- 2What happens to particles in a medium when a progressive wave passes through it?The energy causes particles to move from their equilibrium position to a new position. Displaced particles experience a restoring force which brings them back to their equilibrium position. This causes them to oscillate.
- 3What is a transverse wave?Oscillations that are perpendicular to the direction of energy transfer.
- 4Give examples of transverse waves.EM waves, ripples in water, S-waves in earthquakes
- 5What are longitudinal waves?Oscillations that are parallel to the direction of energy transfer.
- 6Give examples of longitudinal wavesSound waves, P-waves in earthquakes.
- 7Define displacement of a wave.Distance from the equilibrium position in a particular direction.
- 8Define amplitudeMaximum displacement from the equilibrium position
- 9Define wavelengthMinimum distance between two points in phase on adjacent waves
- 10Define a period of oscillationThe time taken for one oscillation or time taken for a wave to move one whole wavelength past a given point
- 11Define frequencyThe number of wavelengths passing a given point per unit time
- 12Define wave speedThe distance travelled by the wave per unit time
- 13What is the wave equation?
- 14What is 1Hz?1 wave passing a given point per second
- 15What is the equation relating the frequency of a wave to its period?f = 1/T
- 16What is a wave profile?A graph showing the displacement of the particles of a wave against the distance along the wave.
- 17What is phase difference?The difference between the displacements of particles along a wave or waves
- 18What is the phase difference of one complete oscillation (in degrees and radians)360
