The threshold frequency v(0) for a metal...

The threshold frequency `v_(0)` for a metalis `7.0 xx 10^(14) s^(-1)`. Calculate the kineticenergy of an electron emitted when radiation of frequency `v= 1.0 xx 10^(15) s^(-1)` hits the metal.
Hing `: KE = h(v-v_(0))`

Text Solution

Verified by Experts

`KE = h(v-v_(0)) = (6.625 xx 10^(-34)) (1.0 xx 10^(15) - 7.0 xx 10^(14))`
`= 1.988 xx 10^(-19) J`
