Define thresold frequency for photoelectric emiision.

Define threshold frequency for photoelectric emission.

Define threshold wavelength for photoelectric effect.

Define the term: Frequency

The thresold frequency for a certain metal is 3.3 xx 10^(14) Hz (Hertz). If the light of frequency 8.2 xx 10^(14) Hz (Hertz) is incident on the metal, find the cut off voltage for photoelectric emission.
