Question

In the 1905 paper explaining the photoelectric effect, Einstein derived expression of entropy of

Answer 1

Explanation:

In 1905, the wave nature of light was an established, incontrovertible fact. In the face of this universally held knowledge, Einstein proposed that light was not a continuous wave, but consisted of localized particles.17-Mar-2005

Light, Einstein said, is a beam of particles whose energies are related to their frequencies according to Planck's formula. When that beam is directed at a metal, the photons collide with the atoms. If a photon's frequency is sufficient to knock off an electron, the collision produces the photoelectric effect.

Answer 2

Answer:

E = W + K.E

Explanation:

E stands for Energy

W stands for threshold energy

And K.E stands for Kinetic Energy

this is the expression...
