What are the properties of light?

Light: It is a form of energy which helps in the sense of vision.
We are able to see objects when light falls on the object and some of light falls reflected back to our eyes.

Properties of Light:
  • Rectilinear propagation of light is the property of light due to which it travels in a straight line.
  • Shadows are formed because light rays travel in a straight line, and they cannot bend around the corners of the objects. The shape of the shadow is also the same as the shape of the object because light travels in a straight-line path.
  •  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 places when the light ray changes its velocity it passes from one medium to another. Index of refraction is used as a means to measure how much light refracts.
  • Dispersion: Dispersion of light is defined as the process in which the white light separates into different colours based on their wavelength when passed through a glass prism.
