What are the main points of Planck's quantum theory of radiation?
Answers
Answer:
1 ) Different atoms and molecules can emit or absorb energy in discrete quantities only. The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum.
2 ) The energy of the radiation absorbed or emitted is directly proportional to the frequency of the radiation.
Explanation:
According to Planck’s quantum theory,
1 ) Different atoms and molecules can emit or absorb energy in discrete quantities only. The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum.
2 ) The energy of the radiation absorbed or emitted is directly proportional to the frequency of the radiation.
Meanwhile, the energy of radiation is expressed in terms of frequency as,
E = h ν
Where,
E = Energy of the radiation
h = Planck’s constant (6.626×10–34 J.s)
ν= Frequency of radiation
