- 1What are transverse waves?Waves in which the direction of vibration of the particles is perpendicular to the direction in which the wave travels.
e.g. electromagnetic waves - 2What are longitudinal waves?Waves in which the direction of vibration is parallel to the direction in which the wave travels.
e.g. sound waves - 3Define plane-polarised/ unpolarisedPlane-polarised waves are transverse waves which are filtered so that they only consisnt of waves in the same plane. Unpolarised transverse waves are waves that are of multiple alignments- can be wiltered by slits/ polariods
- 4Define displacementThe distance and direction of a vibrating particle from its wave's equilibrium position
- 5Define amplitudeThe maximum displacement of a vibrating particle (height of crest/ depth fo trough)
- 6Define wavelengthThe least distance between 2 adjacent particles with the same displacement and velocity at the same time (distance between 2 crests/ troughs)
- 7Define cycleOne complete cycle of a wave is from maximum displacement to the next maxium displacement (e.g. peak to peak/ trough to trough)
- 8Define the period of a waveThe time taken for one complete wave to pass a fixed point
- 9Define frequencyThe number of cycles of vibration of a particle per second (Hz)
