Waves tier 3 vocab

the distance that a certain point in the medium has moved from its rest position

• displacement

• trough

• peak

the highest point above the rest position

• displacement

• trough

• peak

the lowest point below the rest position

• displacement

• trough

• peak

amplitude - the maximum displacement of a point of a wave from its rest position

• amplitude

• displacement

• wavelength

• frequency

distance covered by a full cycle of the wave, usually measured from peak to peak, or trough to trough

• amplitude

• displacement

• wavelength

• frequency

the time taken for a full cycle of the wave, usually measured from peak to peak, or trough to trough

• Frequency

• amplitude

• time period

the number of waves passing a point each second

• Frequency

• amplitude

• time period

A wave that moves in the same direction as the direction in which the particles are vibrating

• Frequent

• Transverse

• longitudinal wave

A wave that moves in a direction at right angles to the way in which the particles are vibrating.

• Frequent

• Transverse

• longitudinal wave

The repeated and regular fluctuations, above and below the same position, eg the pressure of a sound wave or the voltage of an alternating current.

• oscillations

• medium

• matter
