Question

What is Threshold Frequency ?

Explain Brodly​

Answer 1

HEY WELCOME TO MY PERFECT ANSWER-:)

⭕Threshold frequency⭕

We know that a minimum energy is required for a metal to emit electrons. This energy is called work function of the metal. This energy come from the energy of light. Hence we can also say that the light should possess enough energy for the electrons to emit. The energy of light depends on frequency. More the frequency more will the energy of light. Hence we may also say that there is a minimum frequency of the light required for the electrons to emmit. This frequency is called threshold frequency.
