4. Using the following information on the frequency and wavelengths of the colors of light, determine the energy of the photons of light emitted by each crystal. Fill in the answers on the table below. You
will need the formula E = hv where h = Planck's constant = 6.626 x 10-34 Js and v=frequency.
Color
Frequency (Hz)
Energy (J) of photon of light emitted
Red
4.5 x 1014 Hz
X 6.626 x 10-34 JS = 3.0 x 10-19 Joules
Orange
5.0 x 1014 Hz
X 6.626 x 10-34 JS =
Yellow
5.2 x 1014 Hz
Green
5.6 x 1014 Hz
Blue
6.6 x 1014 Hz
Violet
7.3 x 1014 Hz
