What is a threshold frequency?

The threshold frequency is the minimum frequency of radiation that will produce a photoelectric effect.

What is important about the threshold frequency?

The threshold frequency of a metal refers to the frequency of light that will cause an electron to dislodge from that metal. Light below a metal's threshold frequency will not eject an electron. The light above the threshold frequency will eject an electron with some kinetic energy.

How to Calculate Threshold Frequency in Photoelectric Effect?
