$C$

Vedclass · Answer

(C) light emitting diode $(LED)$ is a heavily doped $p-n$ junction diode.It emits light only when it is forward biased,as the recombination of electrons and holes releases energy in the form of photons.It does not emit light when reverse biased.The energy of the emitted light $(E = h
u)$ is approximately equal to or slightly less than the energy band gap $(E_g)$ of the semiconductor material used.Therefore,statement $C$ is incorrect.
