🤔 *How ……..* ⁉
How color of an LED determines?
The material used in the semiconducting element of an LED determines its color. The two main types of LEDs presently used for lighting systems are aluminum gallium indium phosphide (AlGaInP, sometimes rearranged as AlInGaP) alloys for red, orange and yellow LEDs; and indium gallium nitride (InGaN) alloys for green, blue and white LEDs.
Slight changes in the composition of these alloys changes the color of the emitted light.
😳Why❓❓❓
Why can’t chickens🐓🐥 fly?
Chickens actually CAN fly! However, they are not very good at it. Their small wings allow them to fly for only a moment.
They do not have very large wings compared to their body. This means they can’t produce enough lift to overcome their weight!
