frequency*lambda=3E8
frequency=3E8/.001= 3E11 hz
If humans produce a 10mm wavelengh, what is their frequency? Find the energy emitted from humans off of the wavelength given.

Can you help me find the energy emitted off of humans? It is a two parted question.
energy= planck's constant*frequency.
Thank you so much!
h*frequency is the energy per photon
Humans emit a range of electromagnetic frequencies, including 10 mm, but the maximum is emitted around 10 micrometers, not 10 millimeters. The spectrum is approximatley that of a 300 K black body.
If you are talking about deBroglie (matter) waves, that is an entirely different topic. The deBroglie wavelength of matter depends upon its momentum. deBroglie waves do not travel at the velocity of light. They have a phase velocity that is higher and a group velocity that is lower than c.
I am not quite sure what your question is getting at.
