A and B are two metals with threshold frequencies `1.8xx10^(14)Hz and 2.2xx10^(14)Hz`. Two identical photons of energy of 0.825 eV each are incident on them. Then photoelectrons are emitted in take `h=6.6xx10^(-34)j//s`

A and B are two metals with threshold frequencies 1.8 xx 10^(14) Hz and 2.2 xx 10^(14) Hz.Two identical photons of energy 0.825 eV each are incident on them.Then photoelectrons are emitted in (Take h = 6.6 xx 10^(34) Js)

A and B are two metals with threshold frequencies 1.8 xx 10^(14)Hz and 2.2 xx 10^(14)Hz . Two identical photons of energy 0.825 eV each are incident on them. Then, photoelectrons are emitted by (Taking, h = 6.6 xx 10^(-34)J-s )

Light of frequency 8 xx 10^(15) Hz is incident on a substance of photoelectric work function 6.125 eV . The maximum kinetic energy of the emitted photoelectrons is

A photon of energy 8eV is incident on a metal plate with threshold frequency 1.6 xx 10^(15) Hz. The maximum kinetic energy of the emitted photo electrons is (given h= 6 xx 10^(-34) Js )

A photon having 8 eV energy is incident on metal suraface with threshold frequency of 1.6xx10^(15) Hz .Maximum kinetic energy of photoelectron emitted will be……. h=6.6xx10^(-34)JS,c=3xx10^(8)m//s eV=1.6xx10^(-19)JS

The threshold frequency for a certain metal is 3.3xx10^(14) Hz.If light of frequency 8.2xx10^(14) Hz is incident on the metal ,predict the cutoff voltage for the photoelectric emission.
