electromagnetic radiation of frequency v consists of a stream of particles called photons which of the following statements is/are true about photons.
a. as the frequency increases,the number of photons in the beam increases.
b. as the intensity increases the number of photons remains same.
c. the number of photons in the beam are independent of frequency.
d. the number of photons in the beam are independent of intensity pf light.
Answers
Answer:
c. the number of photons in the beam are independent of frequency.
Answer:
The true statement about the photons is the number of photons in the beam is independent of frequency. Hence, the correct option is (c) the number of photons in the beam are independent of frequency.
Explanation:
The energy of a photon is directly proportional to the frequency and the intensity of the photon is defined as the total energy of the photon per unit area. According to Planck's quantum theory, Energy emitted or absorbed is not continuous but is in the form of packets and energy can be related as directly proportional to the frequency. So, as the frequency increases, the energy of the photon also increases. But the frequency of the photon is independent of the number of photons, it depends upon the energy of the photon.
Hence, the number of photons in the beam is independent of frequency.
