Properties of Light

Electromagnetic radiation travels in waves. These waves have a Frequency in hertz(wavelengths per second) and a Wavelength in metres. They travel at the "speed of light", C, which is 3.0 X 108 m/sec.


Directions: Input ONE of the values, calculate the other on paper, then check your answer by clicking "Calculate"

The formula that relates these properties is:
C = Frequency X Wavelength

3 X 108

=

Frequency(hertz)

Wavelength(m)

3 X 108

=

    

The energy of this electromagnetic radiation may also be calculated by using the formula:

E = h X Frequency

E is the energy in Joules and h is Planck's Constant 6.626 X 10-34 J s. So:

Energy(Joules)

=

6.626 X 10-34

Frequency(hertz)

=

6.626 X 10-34
