1) The temperature of the surface of the Sun is 5800 K. Using Wein's Law, compute the wavelength of the color of light at which the Sun has its greatest Emissive Power. Describe this color verbally.

2) Use Planck's quantum equation to compute the energy of the "photons" of the light for the color whose wavelength was identified in part one.

3) Compute the energy of photons of light at opposite ends of the visible spectrum:
Deep Red: wavelength 7000 Angstroms
Violet: wavelength 4000 Angstroms

Solution Summary

Wein's law is applied for Planck's quantum equations. The energy of photons of light at opposite ends are computed.

1) Wein's law is an "inverse-linear" relationship between the wavelength (lambda) with maximum intensity in black body radiation with temperature (T):

lambda_max = a/T

where a is 2898x10^-6 (m K) [that is 2898x10^4 if l is measured in ...
