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 , 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 = 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
