  • The wavefront originating from a point source of light at finite distance is a wavefront.

  • In an isotropic medium, the secondary wavelets centred on every point of a given wavefront are all

  • Consider a medium through which light is propagating with a speed v. Given a wavefront, in order to determine the wavefront after a time interval Δt\Delta t, the secondary wavelets are drawn with a radius.

  • Two points, equidistant from a point source of light, are situated at diametrically opposite positions in an isotropic medium. The phase difference between the light waves passing through the two points is

  • Wave normals to spherical wavefronts can be

  • Huygens’ principle is used to

  • When a ray of light enters air into water?

  • A parallel beam of light travelling in water is incident obliquely on a glass surface. After refraction, its width

  • Light of a certain colour has 1800 waves to the millimetre in air. What is its frequency in water? [n = 43\frac{4}{3} for water]

  • A ray of light, in passing from vacuum into a medium of refractive index n, suffers a deviation d equal to half the angle of incidence. Then, the refractive index is
