Question

How does black body radiation prove particle nature of light?

Answer 1

Answer:

This explains by the discontinuous change in temperature and color change .

Explanation:

according to em wave theory the waves emmit energy in a continuous way but in black body radiation , remember a iron piece when heated. turns red , them blue then white and then blue . this shows that energy supplied is not fixed ,have no fixed wavelength . and it also states that energy is supplied in small amounts and discontinuous , hope you understand.

Answer 2

All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none.
