The de Broglie wavelenght `(lambda)` associated with a photoelectron varies with the frequency `(v)` of the incident radiation as,[`v_(0)` is threshold frequency]:
Maximum kinetic energy (E_(k)) of a photoelectron varies with the frequency (v) of the incident radiation as
The De Broglie wavelenght associated with electron in n Bohr orbit is
The kinetic energy (E_(k)) of a photoelectron varies with the frequency (v) of the incident radiation as which of the following graph ?
The maximu kinetic energy (E_(k)) of the photoelectron varies with frequency (v) of the incident light as shown by the curve:
The de-Broglie wavelength lambda associated with charged particle of charge q, mass m and potential difference V is
The de Broglie wavelenght associated with neutrons in thermal equilibrium with matter at 300 K is:
Derive de Broglie wave equation for material particles. (b) Why does photoelectric emission not take place if the frequency of incident radiation is less than threshold frequency ?
When the light of frequency 2 v_(0) (where v_(0) is threshold frequency), is incident on a metal plate, the maximum velocity of electrons emitted is v_(1) . When the frequency of the incident radiation is increased to 5 v_(0) , the maximum velocity of electrons emitted from the same plate is v_(2) . the ratio of v_(1) to v_(2) is
