Dispersion of Light starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Dispersion of Light.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A prism has a refracting angle of 60°. If the angle of minimum deviation for green light is 40°, calculate the refractive index of the prism for green light.
Describe how dispersion leads to the formation of a rainbow in the atmosphere.
Describe the role of refractive index in the dispersion of light.
Explain why a prism causes dispersion of white light but a glass slab does not.
Explain why the sky appears blue during the day and reddish at sunrise and sunset, relating your answer to dispersion.
Explain why the spectrum produced by a prism is wider for blue light than for red light.
If a beam of white light is passed through a prism and then through an identical inverted prism, what will be observed?
If the refractive index of glass for red light is 1.514 and for violet light is 1.532, which color bends more in the prism?
