This page covers:
amplitude, wavelength, frequency, reflection, refraction, transverse waves, longitudinal waves, specular reflection, diffuse reflection,
Waves transfer energy in the direction they are travelling.
Amplitude - maximum displacement of a point on the wave.
Wavelength - distance between the same point on two adjacent waves.
Frequency - the number of complete waves passing a certian point per second.
Hertz (Hz) - the measurement of frequency.
Oscillations - vibrations.
Transverse waves - the oscillations travel up and down.
Longitudinal waves - the oscillations in the same direction as the wave travels.
Waves can be:
- Absorbed - this transfers energy to the material's energy stores.
- Transmitted - waves travel thorugh the new material.
- Refraction -waves cross a boundary between materials, the angle is changed.
Specular reflection - wave is reflected in a single direction.
Diffuse reflection - wave is reflected by a rought surface and scattered in different directions.
