The essential component in the process of making light is the inter-conversion of energy. Different types of lamps and lighting devices convert energy in different ways and with differing efficiencies. In the tungsten lamp, electrical energy heats a filament to a white-hot glow; thus, thermal energy is converted into light energy. Light emission fr...
One type of light emission – fluorescence – is used in optical brighteners in washing powders. They absorb the small amount of invisible UV light in the Sun’s spectrum, and re-emit it as blue light, making clothes look ‘whiter than white’. Fluorescence is also used in the security markings on banknotes, while phosphorescence(similar to fluorescence...
The world’s energy demands are increasing whereas its non-renewable supplies are limited. One way to address this problem is by using less energy (e.g. with energy-saving light bulbs). Another way is to exploit renewable sources of energy such as the silicon solar cell, which converts light energy into electricity. The original single-crystal cells...
Dec 29, 2017 · Benefits for Life. 1. Photosynthesis for Food formation. The energy from light is trapped as chemical energy and stored as food. As you might have known, this occurs through a process called photosynthesis. Photosynthesis is a concept in biology wherein food is synthesized in green leaves in the presence of light.
Dec 5, 2019 · Chemistry is important in everyday life because: Everything is made of chemicals. You are made of chemicals. So is your dog. So is your desk. So is the sun. Drugs are chemicals. Food is made from chemicals. Many of the changes you observe in the world around you are caused by chemical reactions.

Aug 20, 2023 · Importance of Chemistry in Everyday Life. Chemistry is a scientific discipline that lies between physics and biology in terms of its scope. It is commonly known as “core science” because it serves as a foundational framework for comprehending various basic and applied scientific fields. Chemistry is a scientific discipline that encompasses ...
The Editors of Encyclopaedia Britannica. Light is a primary tool for perceiving the world and interacting with it for many organisms. Light from the Sun warms the Earth, drives global weather patterns, and initiates the life-sustaining process of photosynthesis; about 10 22 joules of solar radiant energy reach Earth each day.
