Question

The threshold energy of a metal is 10 eV. Identify the incorrect option. (E = energy of one photon)


If E = 12 eV, photoelectric effect occurs


If E = 15 eV, kinetic energy of electron is more than option (1)


If intensity of photon increase but energy remain same, then kinetic energy of photoelectron remain same


If intensity of photon increase but energy remain same, then kinetic energy of photoelectron increase
