प्रश्न
Is it always true that for two sources of equal intensity, the number of photons emitted in a given time are equal?
उत्तर
Let the source's area be A, and intensity of the source be I. The energy of each emitted photonis E. Then, the number of photons emitted in a given time will be `n = I/(AE)`
If the areas of the sources and the wavelengths of light emitted by the two sources are different, then the number of photons emitted will be different.
