Consider radiation of wavelength 4000.0 Angstroms, at a temperature of 3000.0 K. A) Using the Rayleigh-Jeans law, calculate the energy per unit volume per unit wavelength. Use Joules and meters. B) Using the Planck radiation law, calculate the energy per unit volume per unit wavelength. Use joules and meters. The equations given were S= (8?kT)/(?^4) and S=[(8?hc)/(?^5)][1/(e^(hc/?kT)-1)]

For A I got 4.067*10^7 and for B I got 3035.48

Also, I tried to calculate the units throughout and I got Joules/meter for A and Joules for B. I am not sure where I messed up.

    To understand electromagnetic radiation and be able to perform calculations involving wavelength, frequency, and energy. Several properties are used to define waves. Every wave has a wavelength, which is the distance from peak to peak or trough to trough. Wavelength, typically given the symbol λ (lowercase Greek "lambda"), is usually measured in meters. Every wave also has a frequency, which is the number of wavelengths that pass a certain point during a given period of time. Frequency, given the symbol...
