Amplitude: the height of the wave measured from the centerline from peak to trough. Intensity: the (amplitude) ^2 in a light beam, it’s a measure of how many photons are in the beam not of the energies of the photons. Speed of wave (m/s): you get this by multiplying the frequency by wavelength. The rate of travel of all electoromagnetic radiation in a vaccume: is a constant (c) which is called the speed og light when light is passed through a prism, a continuous distribution of all possible wavelengths show, each colour coroisponding to different wavelengths traveling through the glass at different rates. When the light given off by an atom passes through a prism, only a few colour show, singling only a few wavelengths pass through. Atoms can only emit light (photon s) of only a few specific energies, that’s y they give the line spectrum.
