Solved 2024 Specimen Paper ICSE Class 10 Physics — Question 5
Back to all questionsWhen sunlight passes through water droplets in the atmosphere it gets dispersed into its constituent colours forming a rainbow. A similar phenomenon is observed when white light passes through a prism.
(a) Which colour will show the maximum angle of deviation and which colour will show the minimum angle of deviation?
(b) If instead of sunlight, a green-coloured ray is passed through a glass prism. What will be the colour of the emergent ray?
(a) When sunlight passes through water droplets in the atmosphere or through a prism, violet light shows the maximum angle of deviation, while red light shows the minimum angle of deviation.
(b) The colour of emergent ray will be green. A prism does not change the colour of light. It just disperses white light into its constituent colours.
