Directions: Copy the equations and tables into your journal. Solve the problems showing all your calculations.

Relationships of frequency and wavelength

frequency = speed of light / wavelength

f = c / λ       where c = 2.998 * 108 m/s

wavelength (nm) Calculation space frequency (Hz)

Relationships of energy and frequency

energy = Planck's constant * frequency

E = h * f       where h = 6.63 * 10-34 J s
