Name the component of white light that deviates the least and the component that deviates the most while passing through a glass prism.

State the causes of dispersion of white light as it passes through a triangular glass prism.

In a mixture of A and B components show negative deviation when

Out of the following, which light is deviated minimum in the dispersion of white light through a glass prism?

Give the relationship between wavelength of light and its angle of deviation, when it is passed through a prism.

Describe the activity to show that the colours of white light splitted by a glass prism can be recombined to get white light by another identical glass prism. Also draw ray diagram to show the recombination of the spectrum of white light.

........ light, while passing through a prism, does not disperse.

Let the resistance of an electrical component remain constant while the potential difference across the two ends of the component decreases to half of its former value. What change will occur in the current through it?

Why do we get different colours in the phenomenon of dispersion of white light through prism?

Which colour of light deviates maximum in the dispersion of white light by a prism?

The refractive indices of the crown glass for violet and red lights are 1.51 and 1.49 respectively and those of the flint glass are 1.77 and 1.73 respectively A prism of angle 6^(@) is made of crown glass .A beam of white light is incident at a small angle on this prism.The other thin flint glass prism is combined white the crown glass prism such that te net mean deviation is 1.5^(@) anticlockwise. (i)Determine the angle of the flint glass prism. (ii)A screen is placed normal to the emerging beam at a distance of 2m from the prism combination.find the distance between red and violet spot on the screen Which is the topmost colour on screen.
