7. Energy, Wavelength, Frequency Calculation Notes

8. Electromagnetic Spectrum

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

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