Vedclass · Answer

(D) An $LED$ (Light Emitting Diode) is a $p-n$ junction diode that emits light when forward biased.Key characteristics of LEDs include:$1$. They operate at low voltages compared to incandescent bulbs.$2$. They do not require any warm-up time.$3$. They have very fast on-off switching capabilities, making them ideal for high-speed communication and display technologies.$4$. The bandwidth of light emitted is typically narrow, not $4000 \ Å - 7000 \ Å$ (which covers the entire visible spectrum).Therefore, the correct statement is that they have fast on-off switching.
