Question

Show graphically the changing of the spectral energy density vs. Frequency plot of a black body radiation if the temperature is increased. Write down the observations from the black body experiment

Answer 1

Answer:

It can be approximated numerically by taking a sum of values of the Planck radiation density times a wavelength interval. The result of dividing the wavelength interval into 100 steps is as follows. For the wavelength range λ1 = nm to λ2 = nm, The radiated power is Pinterval = watts = x10^ watts.

i hope this will help uhh

Answer 2

All objects emit electromagnetic radiation according to their temperature. A black body is an idealized object that absorbs all electromagnetic radiation
