(a) The refractive index of glass is 1.5. What is the speed of light in glass? (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?
(a) The refractive index of glass is 1.5 . What is the speed of light in glass ? (Speed of light in vaccum is 3 xx 10^(8) ms^(-1) ). (b) Is the speed of light in glass independent of colour of light ? If not, which of the two colours, red and violet travels slower in a glass prism ?
Assertion: Speed of light in glass is indep[endent of the colour of light. Reason : the violet colour travels faster than the red light in a glass prism.
Light travels slower in glass than in air because
Calculate angle of dispersion between red and violet colours produced by a flint glass prism of refracting angle 60^@. Mu_v = 1.663 and mu_r = 1.622 .
A student observes the above phenomenon in the lab as a white light passes through a prism. Among many other colours, he observed the position of the two colours Red and Violet. What is the phenomenon called? What is the reason for the violet light to bend more than the red light?
The deviation caused for red, yellow and violet colours for crown glass prism are 2.84^(@),3.28^(@) and 3.72^(@) respectively. The dispersive power of prism material is:
The coloured light having the maximum speed in glass prism is :
