Wave Properties
Wavelength x Frequency=C
C=3.00×10^8
Refraction
Waves bend when passing through different media
Diffraction
Waves bend when going around an edge or through a narrow opening
Interference
Waves either construct or destruct amplitudes
Doppler Effect
Motion-induced frequency shift
Red shift
Light from objects moving away shifts to longer wavelengths
Bright Line Spectra
Emission
Dark Line Spectra
Absorption
