The angle of a crown glass prism of refractive index 1.52 is 6^(@) . What should be the angle of a flint glass prism of refractive index 1.65 , so that the two prisms produce a direct vision prism ?
Assertion:- Fused glass not flint glass, are used to make camera lenses. Reason:- Fused glass has lesser refractive index gradient with wavelength.
In a direct vision spectrograph , there are 3 crown glass prisms and 2 flint glass prisms , each of refracting angle 24^(@) . What should be the angle of the crown glass prism , if the refractive index of crown glass for mean colour is 1.52 and that of flint-glass of 1.65 ?
A prism of crown glass with refracting angle of 5^(@) and mean refractive index = 1.151 is combined with a flint glass prism of refractive index = 1.65 to produce deviation. Find the angle of fliint glass.
A prism of crown glass having angle of refractive as 3^(@) and refractive index = 1.51 is combined with one flint glass prism of refractive index = 1.65 to produce dispersion without deviation. Find the angle of flint glass and net dispersion. Given, mu_(v) = 1.523, mu_(R) = 1.513 (for crown glass) mu'_(v) = 1.665, mu'_(R) = 1.645 (for flint glass)
Light travels with a speed of 2xx 10^(8)ms^(-1) in crown glass of refractive index 1.5. What is the speed of light in dense flint glass of refractive index 1.8 ?
The speed of light in dense flint glass is 3/5 of its speed in air. The refractive index of dense flint glass is
A deviation of 2^(@) is produced in the yellow ray when prism of crown and flint glass are achromatically combined. Taking dispersive powers of crown and flint glass as 0.02 and 0.03 respectively and refractive index for yellow light for these glasses are 1.5 and 1.6 respectively. The refracting angles for crown glass prism will be ........ @ (in degree). (Round off to the Nearest Integer)
The dispersive powers of crown and flint glasses are 0.03 and 0.05, respectively. If the difference between the refractive indices for red and blue is 0.014 crown glass and 0.023 for flint glass, calculate the angle of a flint glass prism which would produce a net deviation of 5^(@) with a crown glass prism of 3^(@) . [ Hint: Net deviation = (mu -1) A+(mu'-1)A' ]
