Light is a form of electromagnetic radiation that is visible to the human eye. It consists of particles called photons, which travel in waves at a constant speed of approximately 186,282 miles per second.
Light travels in straight lines through a vacuum or transparent medium. It can also be reflected, refracted, or absorbed by different materials and surfaces.
The speed of light in a vacuum is approximately 186,282 miles per second. This is known as the speed of light constant and denoted by the symbol 'c'.
White light is composed of all the colors of the visible spectrum. These colors include red, orange, yellow, green, blue, indigo, and violet. When combined, they create white light.
Light is used in a variety of ways in everyday life. It allows us to see objects and colors, it is used in photography and film, it is used in communication through fiber optics, and it is used in various medical and scientific technologies such as lasers and x-rays.
