What is the change in the intensity of red light given off by an incandescent body if the temperature increase

[From: ] [author: ] [Date: 11-05-25] [Hit: ]
in its simplest form.http://en.wikipedia.P=sigma*T^4,where P is the power, sigma the stefan-Boltzmanns constant and T temperature.......
What is the change in the intensity of red light given off by an incandescent body if the temperature increase from 4000 K to 8000 K?

Use Stefan-Boltzmann's Law, in it's simplest form. You can find her somewhere here:

http://en.wikipedia.org/wiki/Stefan%E2%8…

but I think it is something as
P=sigma*T^4,
where P is the power, sigma the stefan-Boltzmann's constant and T temperature.
