Final answer:
The problem in physics requires calculating the number of photons per second from a given power output, using the fundamental relationship between energy, frequency, and Planck's constant for photons.
Step-by-step explanation:
The question involves calculating the number of photons emitted per second by a source of electromagnetic radiation. The solution requires using the power of the electromagnetic source along with the energy of individual photons to determine the total number of photons emitted each second.
We use the formula E = hf to calculate the energy (E) of a photon, where h is Planck's constant and f is the frequency of the radiation. Since power (P) is energy per unit time, we can find the number of photons per second by dividing the total power of the radiation by the energy of a single photon. To summarize the steps, we:
- Calculate the energy of one photon using E = hf.
- Divide the total power output (in joules per second) by the energy of one photon to find the number of photons emitted per second.
The knowledge of electromagnetic radiation and the characteristics of photons is crucial for answering this physics problem.
