Select the incorrect statement :

Options

A. K.E. of photo-electron does not depend upon the wavelength of incident radiation
B. Photoelectric current depends on intensity of incident ratiation and on frequency
C. Stopping Potential depends on frequency of radiation and not on intensity
D. photoelectric current increases when we use photons of high frequency

Answer

A

Explanation

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`
