Electromagnetic theory of Wave: In 1845 Faraday discovered that plane of polarization turns due to the influence of strong magnetic field. This effect is known…

Wave theory of light: Contemporary to Sir Isaac Newton, the famous Dutch scientist Huygens first put forward the wave theory of light in 1678. Later…

Magnitude of Dispersion We know when a white ray of light passes through a glass prism the emitted ray is splitted into seven colors due…

Cause of Formation of Spectrum We know, after refraction of a ray of light through a prism it bends towards the base of the prism.…

The reason behind – Sky Looks Blue Amount of scattering is inverse of the fourth power of wavelength. Scattering of radiation of short wavelength is…

Dispersion of Light – Experiment The phenomenon of splitting a ray of white light into seven fundamental colors while refracting through a prism is called…

Scattering of Radiation When light progresses through a medium, then electrons of the material absorb that radiation. So, due to absorption of energy, those electrons…

Dispersion of Light From ancient times people knew that when light passes through a diamond, valuable stones, and crystals etc different bright colors are produced.…

Angle of Minimum Deviation (δm) We know, when a ray of light passes through a prism deviation takes place due to refraction of light and…

Refraction of Light through Prism A transparent homogeneous medium bounded by three mutually intersecting plane surfaces is called a prism. The surface through which light…
