PROPERTIES OF LIGHT

  • Light is a form of energy.
  • Light always travels along a straight line.
  • Light does not need any medium for its propagation. It can even travel through a vacuum.
  • The speed of light in vacuum or air is, c = 3 x 108 ms-1
  • Since light is in the form of waves, it is characterized by a wavelength (λ) and a frequency (v), which are related by the following equation: c λ (c-velocity of light).
  • Different coloured light has different wavelengths and frequencies.
  • Among the visible light, violet light has the lowest wavelength and red light has the highest wavelength.
  • When light is incident on the interface between two media, it is partly reflected and partly refracted.
