- 1Chapter 3: Waves (Definitions)---
- 2Transverse WavesWhen the waves vibrate at right angles to the spring.
- 3Longitudinal WavesWhen the waves vibrate lengthways down the spring.
- 4DiffractionThe process by which a wave of some kind is spread out as a result of passing through a gap.
- 5Diffraction when the gap width is much wider then the wavelengthLittle to no refraction.
- 6Diffraction when the gap width is slightly wider than the wavelengthDiffraction at the edges of the waves.
- 7Diffraction when the gap is the same width as the wavelengthThe diffracted waves create semi circles around the gap.
- 8F.A.S.T. (when talking about a ray and the normal)Faster Away (from the normal)
Slower Towards (the normal) - 9The angle of incidenceThe angle in relation to the incident ray (the 'original' ray) and the normal (of the mirror/glass block).
- 10The angle of refractionThe angle in relation to the reflected ray and the normal (of the mirror/glass block).
- 11To work out the Refractive index (angle)Sin (angle in air)
--------------------------------------------------------------
Sin (angle in medium) - 12To work out the Refractive index (speed)Speed in air

Speed in medium - 13DispersionWhen white light splits up into its constituent colours (Red to Violet)
