CHE 131 Lecture 9, 2/10/2006 4 A bright light is more intense and has greater amplitude than a dim light. The two waves shown here have the same wavelength, but different amplitudes. amplitude is represented by the height of the wave at its crest. Black Body Radiation Planck’s Quantum Theory E= h ν = hc/ λ where νλ = c E energy h Planck's constant ν →
