Electromagnetic Radiation:

        Infrared radiation is part of a broad electromagnetic spectrum. The relationship between electromagnetic radiation is as follows:
              c
λ =   ^_______
              f

Where:
    λ = Wavelength in meters
    c = Speed of light ( 3 x 10⁸ meters per second )
    f = Frequency in hertz ( cycles per second )

Infrared Spectrum:


Stefan-Boltzmann Law:

        The Stefan-Boltzmann Law gives the total power radiated at a specific temperature from an infrared source. That is, the entire amount of infrared radiation (at a specific temperature) emitted from a given source at all associated wavelengths.

R = (e) x (σ) x ( T⁴ )    Watts / in²

Where:
    σ = Stefan-Boltzmann Constant
        [ 36.58072 x 10 ^-12 W/ in² K]
    e = Emissivity Value of the Source
    T = Surface Temperature of the Source in K (Kelvin.)
