Solution

Threshold frequency is defined as the minimum frequency of incident light which can cause photo electric emission. Cesium is the metal most commonly used in photoelectric emission because it has the lowest threshold frequency. Cesium has a threshold frequency of 4.38 x 10¹⁴ s^-1.

For sodium, threshold frequency is 5.43 x 10¹⁴ s^-1.
