Light and Waves
1. Wave Motion – the transfer of energy from one place to another without the
transfer of matter.
2. Wavefront – a line joining all the crests/troughs on a wave
3. Wave Speed – the distance travelled by a wave per unit time.
4. Frequency – the number of complete oscillations or waves produced per
second.
5. Wavelength – the shortest distance between two consecutive crest or troughs
/ the distance the wave travels in one time period
6. Period – the time taken for one complete oscillation.
7. Amplitude – the maximum displacement of a particle from its equilibrium
(mean) position.
8. Transverse Waves – waves in which the particles of the medium vibrate
perpendicular to the direction of wave propagation.
9. Longitudinal Waves – waves in which the particles of the medium vibrate
parallel to the direction of wave propagation.
10. Reflection – the bouncing back of a wave when it strikes a boundary.
