A teacher is teaching the students certain concepts related to the dispersion of light: An the above figure, a narrow beam of white light is shown to pass through a triangular glass prism. After passing through the prism it produces a spectrum XY on a screen. See the above image and answer the below questions.
1. State the colour seen at X.
(i) Violet
(ii) Red
(iii) Orange
(iv) Green
2. Why do different colours of white light bend through different angles with respect to the incident beam of light?
(i) Due to difference in speed of light.
(ii) Due to difference in speed of air.
3. State the colour seen at Y.
(i) Violet
(ii) Red
(iii) Orange
(iv) Green
4. The process of white light splitting into its constituent colours is termed as?
(i) Dispersion of light
(ii) Snell's law
5. Which colour ray is least deviated by a prism?
(i) Violet
(ii) Red
(iii) Orange
(iv) Green
