What is the importance of light
Answers
Light plays a central role in health, communication, energy, education, agriculture, design and much more. Towards the end of 2014, the Nobel Prize in Physics was awarded to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for the invention of efficient blue light-emitting diodes (LEDs), back in the early 1990s. Since then, more research has been done into the benefits of LED lighting. For example, LEDs use a fraction of the energy that incandescent bulbs use and they last around 70% longer. In relation to design, the directional nature of LEDs allows the lamps and fittings to be designed for optimum efficacy, enabling the designer to illuminate specific objects or outline a space with light.
All most all of the object in the universe depends on light. Light is the part of spectrum of electromagnetic waves .light travels very fast and enables communication in long distances
