“You may think your light is small, but it can make a huge difference in other people’s lives.”
One of the key factors contributing to the abundance of life on the planet is light. Every year on May 16, physicist and engineer Theodore Maiman’s first successful laser operation is commemorated as the International Day of Light. The International Basic Science Programme of UNESCO is in charge of organizing the day, which is recognized by the UN. Worldwide celebrations of the International Day of Light take the form of gatherings and seminars planned by individuals both inside and outside the scientific community.
According to UNESCO, it means increasing collaboration and taking advantage of its potential to promote peace and development. In education, research, art, culture, sustainable development, communications, energy, and medicine, light is a universal symbol of life and is significant.
Consequently, light is a symbol of life, and even in many literary works, light is used to enhance the beauty of those works. “How far that little candle throws his beams! So shines a good deed in a weary world.” This is how William Shakespeare brings out the purity of light in his novel, The Merchant of Venice. Thus, light allows people to glorify their true values.
Other than that, light helps in diversified ways to enrich the environment. For instance, plants develop and create nourishment for other organisms with the help of light. Living things need energy for all of their actions, which is provided by light. It is essential for the creation of vitamin D and oxygen, both of which are required by all living things. Moreover, light is an essential sustainable energy source that people may use to avert a climate change catastrophe.
Light is a fascinating subject with many interesting facts. To begin with, light travels at an incredibly fast speed of 299,792,458 meters per second and can travel through a vacuum, which makes it possible to travel through space. It is a unique wave-particle duality and the color of an object depends on how it reflects or absorbs different wavelengths of light. Light waves are a form of energy and can be harnessed to power things like solar panels. When light passes through a prism, it splits up into different colors, which is why we see rainbows. Finally, the human eye can detect light with wavelengths between 400 and 700 nanometers, making it possible to perceive the colorful world around us.
The sun’s light is pure, regenerative, and has no harmful effects on the environment. On the International Day of Light, let the beams of the sun light up the beacon of your life, which is filled with magical spirits!
