Answer to Problem 1Q

Planck’s made two assumptions, that the energy of radiating oscillator is quantized and the emission or absorption of energy in discrete packets.

Explanation of Solution

Planck made two assumption the first one is the oscillator energy is quantized and the second one is that the oscillator emit or absorb energy in discrete packets. The oscillator mentioned refers to the molecules or the atoms that made up the walls of the blackbody cavity.

These assumptions disregard the classical idea of energy as continuously divisible.

Conclusion:

Planck’s made two assumptions that the energy of radiating oscillator is quantized and the emission or absorption of energy is in discrete packets.
