Polarisation of Light :- polarisation of light is the property of transverse wave that can oscillate with more than one orientation. A light wave that is vibrating in more than one plane is referred to as unpolarised light. The process of transforming unpolarised light into polarised light is known as polarisation of light. If the…
Resolving power of Optical Instruments :- Resolving power of Optical Instruments is the ability of an Imaging device to separate points of an object that are located at a small angular distance or It is the power of an optical instrument to separate far away objects, that are close together into individual images. Consider a…
Diffraction of Light :- Diffraction of light is the slight bending of light as it passes around the edge of an object. The amount of bending depends on the relative size of the wavelength of light to the side of the opening. Explanation of the Intensity distribution in the diffraction pattern :- Figure shows a…
Interference of Light Waves :- When two light waves from different sources meet together, then the distribution of energy due to one wave is distributed by the other. This modification of light energy due to superposition of two light wave is called interference of light waves. Coherent sources :- Those sources of light which emit…
Huygens’s Wave Theory :- Scientist Christian Huygens in 1678 found that light is a form of wave, He found that light propagates in the form of waves and need a medium to propagate in all possible direction, he proposed a theory of wave called Huygens’s wave theory. He told that the secondary source which is…
