NCERT Class 12 Physics Chapter 2 Wave Optics Test Mock Test

This free online test covers Chapter 2, Wave Optics, from the NCERT Class 12 Physics Part II textbook. The 28 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions

Q1.The corpuscular model of light, given by Descartes in 1637 and developed by Newton, differed from Huygens' wave model in that it predicted that:

  • AReflection and refraction could not both be explained by one model
  • BIf a ray bends towards the normal on refraction, the speed of light is greater in the second medium
  • CIf a ray bends towards the normal on refraction, the speed of light is less in the second medium
  • DLight could not travel through a vacuum at all

Q2.In the branch of optics called geometrical optics, a ray is defined as:

  • AThe locus of points of the wave that oscillate in phase
  • BThe straight line joining a source to the eye of an observer
  • CThe line along which the electric field of the wave oscillates
  • DThe path of energy propagation in the limit of the wavelength tending to zero

Q3.A wavefront is defined as a locus of points which:

  • AOscillate in phase, that is a surface of constant phase, with the energy of the wave travelling perpendicular to it
  • BOscillate with maximum amplitude, with the energy travelling along the surface
  • CHave travelled the greatest distance from the source at a given instant
  • DAre at rest at a given instant, the disturbance being zero there
