In physics, the full form of LED is “Light Emitting Diode.” LEDs are semiconductor devices that emit light when an electric current passes through them. They are widely used in various applications such as indicators, displays, lighting, and more due to their efficiency and durability compared to traditional light sources.
LCD stands for “Liquid Crystal Display.” LCDs are electronic displays that use liquid crystals to modulate light passing through them.
They are commonly used in devices such as televisions, computer monitors, and digital watches to display images and information.
In physics, LEDs refer to Light Emitting Diodes.
These are semiconductor devices that emit light when current flows through them.
LEDs are essential components in modern electronics and lighting technology due to their efficiency and longevity compared to traditional incandescent bulbs.
The symbol for LED in physics is typically represented as a diode symbol with arrows pointing away from the diode, indicating the emission of light.
It resembles a regular diode symbol (∆), but with arrows (usually in the shape of rays) indicating the light emission.
LED stands for Light Emitting Diode. The term “LED” originates from its function and structure. “Light Emitting” refers to the emission of light, and “Diode” refers to the semiconductor device that allows current to flow in one direction.
The name “LED” emphasizes its capability to emit light when current passes through it, distinguishing it from other types of diodes that do not emit light.
