Answer: 1 : the quality or state of being intense especially : extreme degree of strength, force, energy, or feeling. 2 : the magnitude of a quantity (such as force or energy) per unit (as of area, charge, mass, or time)
Explanation:
Verified answer
For a given photosensitive material, threshold frequency is the minimum frequency of radiation that is required for photoelectric emission from the material. OR. Intensity is a measure number of photons passing through a given cross section per unit area.
