Out of blue and red light,which is devated more by a prism?Give reasons.

Which kind of light is scattered more as its why?

Write deviation formula for prism.

Violet colour is seen at te bottom of the spectrum,when white light is dispersed by a prism.Why?

Out of white phosphorus and red Phosphorus, which one is More reactive and why?

Will the focal length of a lens for red light be more, same or less than that for blue light?

Name the factors on which the deviation produced in the path of a ray oflight by a prism depends.

(a) The refractive index of glass is 1.5. What is the speed of light in glass ? (Speed of light in vacuum is 3xx10^(8)"m/s" ) (b) Is the speed of light in glass independent of the colour of light ? If not, which of the two colours red and violet travels slower in a glass prism ?

Prism A prism is a portion of transparent refracting medium bounded by two plane surfaces inclined to each other at a certain angle, and the angle between the refracting faces is called angle of the prism denoted by A. The deviation produced by the prism is maximum for violet (delta_v) and minimum for red (delta_r) colour. The deviations suffered by a ray in passing through a small angled prism is
