Energy, Wavelength, Frequency Calculation Notes

Electromagnetic Spectrum

Calculating Wavelength and Frequency C= 3.0 x 108 m/s (speed of light) λ = wavelength (meters) ν = frequency (Hertz or 1/seconds)

Calculating Energy and Frequency Planck came up with the equation E= hν E = Energy (Joules) h = Planck’s Constant 6.626 x 10-34 J*s ν = frequency (Hertz or 1/seconds)

Calculation Examples

Energy, Wavelength, Frequency Practice Complete the practice at your desk. Ask Mr. Klotz for help if you have questions.
