Vedclass · Answer

(B) wavefront is defined as the locus of all points that are in the same phase of oscillation. Thus,statement $A$ is correct.Light rays are defined as lines perpendicular to the wavefront,indicating the direction of wave propagation. Thus,statement $C$ is correct.Huygens proposed the existence of an 'ether' medium to explain the propagation of light waves,but the Michelson-Morley experiment later proved that no such medium exists. Thus,statement $D$ is correct.Wavefronts can take various shapes depending on the source and the medium,such as cylindrical,spherical,or plane. Since wavefronts are not restricted to only spherical or plane shapes (e.g.,a line source produces a cylindrical wavefront),statement $B$ is incorrect.

$A$ parallel cylindrical beam of light propagates in a medium with a refractive index $\mu(I) = \mu_0 + \mu_2 I$,where $\mu_0$ and $\mu_2$ are positive constants and $I$ is the intensity. As the intensity of the light decreases,the radius increases. The initial shape of the wavefront is:

The wave front is a surface in which
