A thin prism produces an angular dispersion of 24. If the refracting angle of the prism is 3^(@) , and the refractive index of the material of the prism for red colour is 1.55 . What is the refractive index of its material for violet light ?
The refractive index of glass with respect to air is 3/2 and the refraction index of water with respect to air is 4/3 . The refractive index of glass with respect to water will be:
The refractive index of water and glass with respect to air is 1.3 and 1.5 respectively, what will be the refractive index of glass with respect to water?
Which has higher refractive index: water or glass?
A beam of light consisting of red, green and blue colours is incident on a right angled prism. The refractive index of the material of the prism for the above red, green and blue wavelengths are 1.39, 1.44 and 1.47, respectively.
Find the refractive index of water with respect to glass if the refractive index of water is 4/3 and the refractive index of glass is 3/2.
