## Homework Statement

Calculate the spectral radiant exitance for a 10um black body at the following temperatures: -12.0°C, 0°C, 12°C, 1600 K, and 2500 K

Known:

wavelength = 10um

temperature = see above

## Homework Equations

Planck's equation I think

## The Attempt at a Solution

No idea. I can't figure out the equation (I am a major noob at this). The given equation is:

M

^{λ}= C

_{1}/ (λ

^{5}[e

^{(C2/λT)}- 1)

λ = wavelength in micrometres

T = temperature in Kelvin

C

^{1}and C

^{2}are supposed to be Planck's constants. What does the "e" mean?
