Select the incorrect statement :

Answer»

K.E. of photo-electron does not DEPEND upon the WAVELENGTH of INCIDENT radiation
Photoelectric current depends on intensity of incident ratiation and on frequency
Stopping Potential depends on frequency of radiation and not on intensity
photoelectric current increases when we use photons of HIGH frequency

Solution :KE = `h(UPSILON - upsilon_0) , KE alpha (upsilon - upsilon_0)`
We know `lambda alpha 1/(upsilon)therefore KE alpha 1/(Delta lambda)`
`therefofe ` KE dependent on `lambda`
