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.
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 1 × 10 −11 metres to radio waves measured in metres.
Every form of light—seen and unseen—has something in common: it travels in waves, and it carries energy. What distinguishes one type from another is its wavelength and frequency.
Light in physics, its properties, colours, and behaviour, including reflection, refraction, and optics explained clearly.
