Frequency
The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
V=1/T
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
It is based on the principle that conductivity of a semiconductor enhances with increase in the intensity of incident light. In this, a thin layer of some semiconductor (as
