   Following are the properties of light: Reflection of light: Every light follows the law of reflection which states that the angle of incidence is equal to the angle of reflection. Refraction of light: Refraction of light takes place when the light ray changes its velocity it passes from one medium to another.

   Is light a form of radiation?

   • In fact visible ‘light’ is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like ‘wave-packets’, called photons, that travel constantly at the speed of light (about 300 000 kilometres per second). What Colour means love?

   What is a range of wavelengths called?

   • The range of wavelengths, from super short to very, very long, is known as the light spectrum. Whatever its wavelength, light will radiate out infinitely unless or until it is stopped. As such, light is known as radiation. Light’s formal name is electromagnetic radiation. All light shares three properties. It can travel through a vacuum.

   Why can a luminous object be seen?

   • Luminous objects, like the Sun, can be seen because they produce their own light. The light travels in a straight line directly from the source to your eye. Non-luminous objects, like the Moon, do not produce their own light, but they can be seen because they reflect light from luminous objects.

   How do light sources work?

   • Light sources operate at specific ranges of the electromagnetic spectrum. This spectrum includes all the different types of electrical and magnetic energy in the universe. They are divided according to the size of the waves in which they travel. The visible light we use to see is a tiny part of this spectrum.
