Based on his `alpha`- ray scattering experiment, Rutherford proposed the nuclear model of an atom. The threshold frequency v0 for a metal is `6.2xx10^14s^(-1)`. Calculate the K.E. emitted for an electron when the radiation of frequency `v=8.7xx10^14s^(-1)` strikes the metal.

Text Solution

Verified by Experts

`K.E=1/2mv^2=hgamma-hgamma_0=h(gamma-gamma_0)=6.626xx10^(-34)(8.7xx10^14-6.2xx10^14)6.626xx10^(-34)xx2.5xx10^14=1.656xx10^(-19)J`
