Question

Explain Wave front theory with illustrations​

Answer 1

Answer:

Explanation:

Huygen's principle states that every point on the wavefront may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light. The new wavefront is the tangential surface to all these secondary wavelets. Thus, it is a geometrical method to find the wavelength.wavefront: The surface defined by the locus of points that have the same phase, i.e., have the same path length from the source. ... For rays diverging from a point, or converging toward a point, the wavefront is spherical.Wavefront. A wavefront is a surface or line in the path of wave motion on which the disturbances at every point have the same phase. Depending upon the source of light, wavefronts can be of three types: spherical wavefront, cylindrical wavefront and plane wavefront.There are three types of wavefronts. 1. Spherical wavefront : A wavefront originating from the point source of light at finite distance is called spherical wavefront....

Answer 2

Explanation:

The phenomenon in which compounds having different structural formulae have the same molecular formula is called structural isomerism

Example: Molecular Formulae= C4H10
