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 |
