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.
