A prism can be used... but there are probably other ways.
That's hard to compare; improving energy efficiency often requires you to change a complete device for another device, for example, a light-bulb for a light-bulb that uses different technology. Whether the new device will live longer depends on the technology used.
Inverter
In electronics, bidirectional device is device which can be used by both directions like resistor. It does not effect on characteristics of device if we change the terminals of that device.
A light dependent resistor (LDR) is used for the detection of light.A photodiode is a device that converts light into an electrical current.
In Light Emitting Diodes when electron jumps from one state to another state it emits some energy in the form of light. And the light will be different for different type of semi conductor materials used for making for it. So, in conclusion Light in LED is a result of output process.
A transformer.
it is a device which is used to change the resistance of circuit.
a tv remote used to change channels
no it cannot be used as a sharing device.
A laser.
A prism.
no it cannot be used as a sharing device.
