Study the diagram carefully and answer the question that follow. Complete the above diagram indicating the names of the emerging colours in correct sequences.

When white light passes through a glass prism, it splits into its constituent colours as shown in the diagram below: The sequence of the colours so formed can be given using the acronym VIBGYOR where violet is towards the base of the prism while red is towards its apex.

Study the diagram carefully and answer the question that follow. Give an example of the phenomenon occurring in (i) daily life, (ii) nature.

In daily life dispersion is easily visible on a soap bubble where beautiful colour patterns are seen. In nature, the best example of dispersion is rainbow formation during or after a rain shower or near a fountain.

Study the diagram carefully and answer the question that follow. Name the colour which deviates the (i) most (ii) least.

When white light enters a glass prism, it undergoes refraction and different colours deviate differently according to the refractive index offered by the material of the prism. In this course, the violet colour deviates the most and the red colour deviates the least.

Study the diagram carefully and answer the question that follow. Explain a method to recombine the separated colours to get back white light.

When white light passes through a glass prism, it disperses into its constituent colours and form a spectrum, known by the acronym VIBGYOR. When these colours are made to pass through another prism which is kept inverted with respect to the first prism, they recombine to form white light. This is because, the inverted prism makes the light of different wavelengths bend towards each other and thus forms white light.
