EM Spectrum
The distance between any two corresponding points on successive oscillations of a wave, such as from peak to peak.
Wavelength
A self-luminous celestial body consisting of a mass of gas held together by its own gravity in which the energy is generated by nuclear reactions in its interior.
Star
A plot of the surface temperature (color) of stars vs. their luminosity (brightness)
