Answer 2

Dear Student,

◆ Threshold frequency -

• Threshold frequency is the minimum frequency of incident light which can cause emission of photo-electrons from the metal surface.
• Photo-emission of electrons is not possible below threshold frequency.
• Threshold frequency of particular surface depends on nature of its material.

Hope this helps you. Thanks dear for the question...
