light waves
| Question | Answer |
|---|---|
| what is light | light is enery you can see |
| what is refection | light bouncing of a surfuce |
| what is refraction | the bending of light ray as they enter a new mediun |
| ROYGBIV | red, orange, yellow, green, blue, indigo and violet. |
| ampltude | The amplitude, a, of a wave is the distance from the centre line (or the still position) to the top of a crest |
| wave lenth | the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave. 2. |
| crest | A crest is the highest point on a wave |
| trough | trough is the lowest point of the wave |
| frequnency | The frequency, of a wave is the number of waves passing a point in a certain time. |
| photons | a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass |
| transverse wave | a wave vibrating at right angles to the direction of its propagation. |
| color spectrum | The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum |
