NCERT Solutions for Class 12 Physics Chapter 10: Points To Remember

Some of the important points to remember from Class 12 Physics Chapter 10 are as follows:

  • A wavefront is the locus of points in a propagating wave that oscillate in phase. As a result, a wavefront is defined as a surface with a constant phase.
  • A point source’s wavefront will be spherical, while a distance source’s wavefront will be planar.
  • The phenomenon of light refraction could not be explained by Newton’s corpuscular model of light, but it was successfully explained by Huygens’ wave nature of light.
  • The Doppler effect refers to changes in light frequency caused by the motion of the source. But when the source moves towards the observer, the frequency rises (blue shift), and when the source moves away, the frequency falls (red shift).
  • A plane polarised wave is one in which all of the disturbances occur in the same plane.
  • A polaroid is a material that allows disturbances only in one direction, known as the pass axis.
  • The Brewster’s angle is the angle of incidence at which the reflected wave is completely polarised.
  • The angular separation between two distant objects that can be clearly seen through a lens is given Δθ=0.61λ/a.
  • Huygens’ wave theory can be used to verify the laws of reflection and refraction.
  • Every point along a wave front acts as a light source, emitting secondary wavelets.
  • Secondary wavelets spread with the speed of light in all directions in space (vacuum).
