Question

The refractive indices of kerosene,turpentine and water are 1.44 , 1.47 and 1.33 respectively. In which of these light travels faster show numerically?

Answer 1

$\underline{\underline{\Huge\mathfrak{Answer ;}}}$

• More the Refractive index less is the speed of light travelling in that medium.

So, the relation between the speed of light in Kerosene , Turpentine and Water is ;-

Water >Kerosene>Turpentine

See, more refractive index means more loss in the energy and more the deviation i.e. the photons lose out their energy and they change their wavelength but frequency remains constant .
