Question

Every metal has a definite work-function. Then, all photoelectrons do not come out with same kinetic energy, if incident radiation is monochromatic because (A) KE of emitted electron depends on number of photons absorbed (B) KE of emitted electron depends on energy of absorbed photon and each photon may be of different energy (C) all electrons in an atom do not have the same energy level (D) all electrons have same kinetic energy

Tardigrade Admin · Accepted Answer

When an electron absorbs sufficient energy, it is emitted and carries remaining energy as its KE. Part of energy absorbed is spent in overcoming attraction from metal surface and in collision.

K E_{m a x} = 4 v - ϕ = 0.35 e V

Q. Every metal has a definite work-function. Then, all photoelectrons do not come out with same kinetic energy, if incident radiation is monochromatic because

KE of emitted electron depends on number of photons absorbed

KE of emitted electron depends on energy of absorbed photon and each photon may be of different energy

all electrons in an atom do not have the same energy level

all electrons have same kinetic energy

When an electron absorbs sufficient energy, it is emitted and carries remaining energy as its KE. Part of energy absorbed is spent in overcoming attraction from metal surface and in collision. KEmax​=4v−ϕ=0.35eV
