The wave theory of light was given by
Maxwell
Planck
Huygen
Young
(c)Wave theory of light is given by Huygen.
Explain the reflection of plane wavefront from concave mirror.
Figure shown plane waves refracted for air to water using Huygen's principle $a, b, c, d, e$ are lengths on the diagram. The refractive index of water wrt air is the ratio.
The figure shows a surface $XY$ separating two transparent media, medium – $1$ and medium- $2$. The lines $ab$ and $cd$ represent wavefronts of a light wave traveling in medium- $1$ and incident on $XY$. The lines $ef$ and $gh$ represent wavefronts of the light wave in medium- $2$ after refraction.
The phases of the light wave at $c, d, e$ and $f$ are $\phi_c,\phi_d, \phi_e$ and $\phi_f$ respectively. It is given that $\phi_c \neq \phi_f.$
Consider a point at the focal point of a convergent lens. Another convergent lens of short focal length is placed on the other side. What is the nature of the wavefronts emerging from the final image ?
Write Huygen's principle and explain it.
