Dispersion of Light

a dichromatic...

Question

a dichromatic light of wavelength 5600A and 6300A pass through a prism of crown glass. then compare the deviation of both the lights

Open in App

Solution

Wavelength is inversely proportional to wavelength.therefore the dichromatic light with wavlength 5600A will be deviated than thant with 6300A.

1.632

for flint glass. Then :

Q. The refractive indices of the crown glass for blue and red lights are 1.51 and 1.49, respectively, and those of the flint glass are 1.77 and 1.73, respectively. An isosceles prism of angle

6^{o}

is made of crown glass. A beam of white light is incident at a small angle on this prism. The other flint glass isosceles prism is combined with the crown glass prism such that there is no deviation of the incident light. Determine the angle of the flint glass prism in degrees.
