Question

Calculate the Einstein temperature if the Einstein frequency is 10^12HZ

Answer 1

Answer:

The present day accepted value of Planck's constant is h = 6.62 × 10−34 joule-sec. Intensity of light beam is merely the number of photons in the beam, doubling the light intensity simply doubles the number of photons and thus doubles photoelectric current. It does not change the energy hν of the individual photons.
