Question:

Explain HOW and WHY the Radiation looks like that for a Intensity against Wavelength Graph: 1. The Sun 2. You.

Author: eric_galvao



Answer:

1. So Radiation will cover through Energy Values, Wavelengths and Frequencies. And as something gets Hotter, Every Wavelength will get Hotter - but it'll be Very Quick for the Shorter Wavelengths because of the fact that Shorter Wavelengths = More Energy being Transferred so the Peak will Change from the Middle of the x Axis [Long Wavelengths] to the Right Side of the Graph [Shorter Wavelengths. 2. You will Emit Infra Red Radiation, so the Peak of the Graph will be where the Wavelength Matches the Infra-Red Section
