Question

what is harnessing of light​

Answer 1

$\huge \mathfrak \red{answer}$

Harnessing Light" means exactly what it says - we control and make use of this natural resource in whatever way we can for the benefit of mankind. Like we have harnessed the wind energy, and we have harnessed solar energy, we have always been harnessing light. From the days of Edison's incandescent lamp with the familiar tungsten filament to the LEDs of today, we light up our homes. Just a few years ago, we thought of LEDs as nothing more than the tiny red lights used as indicators in equipment, but times have changed! With more and more people realizing the energy-efficiency benefits of LED lighting, it seems that everything from headlights to homes and TVs are now being lit up by the versatile light emitting diodes.
