Question

A blackbody curve relates _____. intensity of radiation to energy intensity of radiation to wavelength wavelength to energy surface area to wavelength

Answer 1

Intensity of radiation to wavelength

Answer 2

A blackbody curve represents the relation between intensity of radiation with wavelength.

Here in this curve we can see that all ideal blackbody radiates almost all wavelength of radiations and these radiations are of different intensity.

here intensity will be maximum for a given wavelength of radiation and the relation of this wavelength with the temperature of the object is given by Wein's law

It is given by

$\lambda = \frac{b}{T}$

now if we increase the temperature the maximum intensity for which wavelength is given will shift to the left.

Using this all we can also compare the temperature of two blackbody for which radiation graph is given to us.
