Homework Statement

Does a blackbody at 200K emit twice as much total radiation as when its temperature is 100K?

The Attempt at a Solution

I'm not sure, but I think it is yes because if the temperature is doubled, then the energy of the photons will be doubled, therefore it will emit twice as much radiation. Is this correct?

 

[Redbelly98]

There is a well-known equation that relates radiated power to temperature of a blackbody. It is surely in you class notes or textbook.

 

[clarkandlarry]

the only equation in my notes with temperature in it is:
(wavelength) x temperature = 0.002898mK

i don't know how this relates to the question though

 

[Redbelly98]

There should be another equation, involving radiated power. And temperature raised to some integer power. It probably has a Greek lowercase "sigma" in it as well.

If not in your notes, check the textbook.
