alleryIncreasing the intensity of light of a given wavelength increases the:
ANumber of photons
BNucleus of photons
CNeutrons in photons
DNature of photons
Answer & Solution
Correct answer: A. Number of photons
1. The energy per photon is fixed by the wavelength.
2. Increasing intensity only increases the number of photons per second crossing an area.
3. Each photon still carries the same energy.
