Give reason
Yellow shirt is covered with a material that absorbs light of blue colour .

In Young's experiment one slit is covered with a blue filter and the other (slit) with a yellow filter then the interference pattern

Give reason We wear dark coloured clothes in winter and light coloured clothes in summer.

What would be the colour reflected if the material absorbs blue?

A black paper absorbs light of all the colours and reflects none.

The diagram alongside shows a beam of light (red + blue) incident normally on an equilateral triangular prism. If the critical angle for the material of prüsm is 60^@ for the light of red colour, complete the diagram showing the path of light of each colour emerging out of the prism. Mark in the diagram the angles wherever necessary.

You are given four sources of light each one providing a light of a single colour-red, blue,green and yellow. Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is 90^@ . Which of the folowing statements is correct it the source of yellow light is replaced with that of other lights without changing the angle of incidence ?

With respect to air critical angle in a medium for light of red colour [lambda_(1)] is theta . Other facts remaining same, critical angle for light of yellow colour [lambda_(2)] will be

A spinner is coloured by 3 different colours-yellow, blue and red in 12 equal sectors. After spinning the wheel, what is the probability that (i) wheel stops at yellow colour. (ii) wheel stops at red colour. (iii) wheel stops at blue colour.

Give reasons why? Commercial concentrated nitric acid is yellow in colour but when it is diluted with water, it turns colourless.
