When a metallic surface is illuminated by a light of frequency `8xx10^(14)`Hz, photoelectron of maximum energy 0.5 eV is emitted. When the same surface is illuminated by light of frequency `12xx10^(14)` Hz, photoelectron of maximum energy 2 eV is emitted. The work function is

When a certain metal was irradiated with light of frequency 1.6xx10^(16)Hz , the photoelectrons emitted had twice the kinetic energy as photoelectrons emitted when the same metal was irradiated with light of frequency 1.0xx10^(6)Hz . Calculate the threshold frequency (v_(0)) for the metal.

When certain metal was irradiated with light of frequency 1.6xx10^16 Hz the photoelectrons emitted had twice the kinetic energy as did photoelectrons emitted when the same metal was irradiated with light of frquency 1xx10^16 Hz Calculate threshold frequency of the metal

When a certain metal was irradiated with light of frequency 3.2 xx 10^(16) Hz, the photoelectrons emitted had twice the kinetic energy as did photoelectrons when the same metal was irradiated with light of frequency 2.0 xx 10^(16) Hz . The threshold frequency for the metal is

A photon of energy 8 eV is incident on a metal surface of threshold frequency 1.6 xx 10^(15) Hz , then the maximum kinetic energy of photoelectrons emitted is ( h = 6.6 xx 10^(-34) Js)

What a certain was metal was irradiatiobn with light of frequency 1.6 xx 10^(16) Hz the photoelectron emitted but the kinetic energy as the photoelectron emitted when the same metal was irradiation with light of frequency 1.0 xx 10^(16) Hz .Calculate the threslold frequency (v_(0)) for the metal

What a certain was metal was irradiatiobn with light of frequency 1.6 xx 10^(16) Hz the photoelectron emitted but the kinetic energy as the photoelectron emitted when the same metal was irradiation with light of frequency 1.0 xx 10^(16) Hz .Calculate the threslold frequency (v_(0)) for the metal

If a light with frequency 4xx10^(16) Hz emitted photoelectrons with double the maximum kinetic as are emitted by the light of frequency 2.5xx10^(16) Hz from the same metal surface, then what is the threshold frequency (v_(0)) of the metal?

If a light with frequency 4xx10^(16) Hz emitted photoelectrons with double the maximum kinetic as are emitted by the light of frequency 2.5xx10^(16) Hz from the same metal surface, then what is the threshold frequency (v_(0)) of the metal?
