CHAPTER VI INFO SHEET
λ = wavelength = distance between two maxima or minima
Units of length (nm)
ν = frequency = number of maxima or minima passing past a fixed point per unit time
Units of inverse time (cycles/sec or Hz)
E = energy = h x ν
Units of energy (J)
c = speed of light = λ x ν = 3.00 x 108 m/sec
h = Planck’s constant = 6.626 x 10-34 J.sec
