Question

Einstein's photoelectric equation states that Ek=hν-W . In this equation, Ek refers to (A) kinetic energy of all ejected electrons (B) mean kinetic energy of emitted electrons (C) minimum kinetic energy of emitted electrons (D) maximum kinetic energy of emitted electrons

Tardigrade Admin · Accepted Answer

Ek refers to maximum kinetic energy of emitted electrons. The energy of photon absorbed is used in doing work against forces of attraction and imparting kinetic energy to electron.

Q. Einstein's photoelectric equation states that $E_{k} = h ν - W$ . In this equation, $E_{k}$ refers to

kinetic energy of all ejected electrons

mean kinetic energy of emitted electrons

minimum kinetic energy of emitted electrons

maximum kinetic energy of emitted electrons

$E_{k}$ refers to maximum kinetic energy of emitted electrons. The energy of photon absorbed is used in doing work against forces of attraction and imparting kinetic energy to electron.

Q. Einstein's photoelectric equation states that Ek​=hν−W . In this equation, Ek​ refers to
