What is light in simple words?
Light, or Visible Light, commonly refers to electromagnetic radiation that can be detected by the human eye.
Light can also be described in terms of a stream of photons, massless packets of energy, each travelling with wavelike properties at the speed of light..
What type of energy is light?
electromagnetic radiationLight energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

What is light write its properties?
Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. … If a single wavelength is present we say that we have monochromatic light. If all wavelengths of visible light are present, our eyes interpret this as white light.
What is light BYJU’s?
Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun. … The energy is released in the form of a photon and more photons come out as the substance gets hotter.
