How does black body radiation explain particle nature of light?

Americast. It is given in my book that the phenomenon of black body radiation can be used to prove the particle nature of light. They have also mentioned that the wavelength-intensity relationship "cannot be explained satisfactorily on the basis of wave theory of light."

Any object with a temperature above absolute zero emits light at  all wavelengths. If the object is perfectly black (so it doesn't reflect any  light), then the light that comes from it is called blackbody radiation.

The energy of blackbody radiation is not shared evenly by all  wavelengths of light. The spectrum of blackbody radiation (below) shows that  some wavelengths get more energy than others. Three spectra are shown, for three  different temperatures. (One of the curves is for the surface temperature of the  Sun, 5770 K.)

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
