A metal surface fo threshold frequency ` 5 . 3 xx 10^(14) "src" ^(-1)`. Is exposed to a photon fo radiation having energy ` 3. 5 xx 10 ^(-19)` J will it exhibit photoelectic effect ?

Explanation

` E//"photon" = hv "or" v = ( 3.5 xx 10^(-19))/(6.626 xx 10^(-34)) `
` = 5. 28 xx 10^(14) sec ^(-1)`
Since the frequency of the radiaiton used ` v lt v_0` i.e., threshold frequency or minimum frequency to show photoelectric effect it will not show photoelectric effect .
