- 1frequencythe number of waves passing a point each second
- 2time periodthe length of time it takes one wave to pass a given point
- 3wavelengththe distance from a point on one wave to the same point on the next wave
- 4amplitudethe maximum distance of a point on the wave away from it's rest position
- 5velocitythe speed of a wave in the direction it is travelling
- 6transversea wave that oscillates at a right angle
- 7longitudinala wave that flows in one direction
- 8a cycleone complete oscillation
- 9reflectedwhen a wave 'bounces' off something
- 10refractedthe wave passes into the new material but changes the direction it is travelling
- 11transmittedthe wave passes through the material and is not absorbed or reflected
- 12ray diagramsa way of modelling what happens when light is reflected/refracted
- 13normala line drawn at right angles to the barrier
- 14absorbedthe wave disappears as the energy is carried into the material
- 15law of reflectionwhen waves are reflected the angle of reflection is equal to the angle of incidence
- 16total internal reflectionif the angle of incidence increases further the light is completely reflected inside the glass
- 17electromagnetic wavecaused by vibrating electrons and magnetic fields
