Describe a simple prism spectrometer. Trace the course of rays through it.

Three rays of light -red(R),green(G) and blue(B)-are incident on the face AB of a rigth-angled prism ABC as shown in Fig.3.27. The refractie indices of the material of the prism for red,green and blue wavelengths are 1.39,1.44 adn 1.47 respectively. Trace the path of the rays thruogh the prism.How will the situation change,if these rays were incident normally on one of the faces of an equilateral prism?

Draw ray diagram to show how a right angled isosceles prism can be used to deviate the ray through 90^@ .

Three light rays red, green and blue are incident on a right angled prism 'abc' at face 'ab'. The refractive indices of the material of the prism for red, green and blue wavelengths are 1.39, 1.44 and 1.47 respectively. Out of the three which colour ray will emerge out of face 'ac'? justify your answer. Trace the out of the face 'ac'? Justify your answer. Trace the path of these rays after passing through face 'ab'.

Draw ray diagram to show how a right angeld isosceles prism can be used to deviate the ray through 180^@

Describe Spectrometer. How will you use it to determine the refractive index of prism?

When a ray of light passes through a glass prism then a spectrum is obtained on the screen Name the seven colours of spectrum in a serial order

A ray of light is sent through the point P(1,2,3) and is reflected on the XY plane. If the reflected ray passes through the point Q(3,2,5) then the equation of the reflected ray is

A person had roti and dal for his lunch. Trace the changes in those during its passage through the alimentary canal.

At what angle ,a ray of light will incident on one face of an equilateral prism,so that the emerget ray may graze the second surface of the prism(=1.5)?
