The threshold frequency of a metal is `f_(0)`. When the light of frequency `2f_(0)` is incident on the metal plate, the maximum velocity of electrons is `v_(1)`. When the frequency of the incident radiation is increased to `5f_(0)`, the maximum velocity of electron emitted is `v_(2)`. Find the ratio of `v_(1)` to `v_(2)`.
