WebQues: If in a photoelectric experiment, the wavelength of incident radiation is reduced from 6000 Å to 4000 Å then (a) Stopping potential will decrease (b) Stopping potential … WebExperimental observation of photoelectric emission Even though photoemission can occur from any material, it is most readily observed from metals and other conductors. This is because the process produces a charge imbalance which, if not neutralized by current flow, results in the increasing potential barrier until the emission completely ceases.

WebAlthough a photon is massless, it still has momentum. Einstein's E = mc^2 formula is actually a special case of the special relativity formula E^2 = p^2c^2 + m^2c^4, where p is momentum, m is rest mass, E is energy, and c is the speed of light. If you substitute 0 for m (because a photon is massless), and E = hv (the formula for the energy of a ... WebIf f > f t, then a single light quantum (called a photon) of energy E = h f is sufficient to liberate an electron, and any residual energy carried by the photon is converted …

WebExperimental data reveal that it is the frequency of the incident wave that impacts this current.
