Question

what is minimum threshhole frequency​

Answer 1

Explanation:

$\huge\blue{HELLO\:MATE}$

Threshold frequency is the minimum frequency of the incident radiation below which photoelectric emission is not possible irrespective of the intensity of the incident radiation.At the limiting frequency called the " threshold frequency ", the kinetic energy of the released electron is zero. Setting KE = 0 and replacing f by fth, we get: h fth = Wo or fth = Wo / h. The above formula gives the threshold frequency, fth .
