Waves, light and spectra
A wave is a propagating disturbance that can transfer energy and information without requiring a net transport of matter over the same distance.

Frequency, wavelength and propagation speed are linked; what oscillates locally depends on the kind of wave and its medium.
Spectroscopy studies how matter emits, absorbs or scatters electromagnetic radiation as a function of wavelength, frequency or energy.
