Light warehouse jobs scarborough part time. ) that we can see. Light travels very rapidly, but it does have a finite velocity. Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings. What is Light? Light is a type of energy that enables us to see with our eyes. In order to see, there must be light. It is just a form of energy (also called electromagnetic energy) that travels at a constant speed from one place to another and reflects from the objects. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres. Light shines on an object, then bounces off, or reflects, back to our eyes. We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember-- light is energy. That is the reason we can see objects during daytime with the sunlight, or with a light bulb in the night. The study of light and its interaction with matter is termed optics. Our eyes are sensitive to a certain kind of light called visible light. The meaning of LIGHT is something that makes vision possible. Synonym Discussion of Light.

Light is electromagnetic radiation that can be detected by the human eye. Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered. But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks disjointed.
