LIGHT - (WHAT IS LIGHT + HOW WE SEE + FACTS) - SCIENCE4FUN
light isn’t made of matter, so it doesn’t have mass. 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. When it hits our eye, we see the objects from which the light is … From science4fun.info

Simply stated, light is nature's way of transferring energy through space. We can complicate it by talking about interacting electric and magnetic fields, quantum mechanics, and all of that, but just remember-- light is energy. Light travels very rapidly, but it does have a finite velocity. From blair.pha.jhu.edu
What is Light? Light is a type of energy that enables us to see with our eyes. Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings. That is the reason we can see objects during daytime with the sunlight, or with a light bulb in the night. From learn-physics.org

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. From science.howstuffworks.com
Jul 28, 2025 What is light in physics? Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about … From britannica.com
The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. From en.m.wikipedia.org
