Dispersion of Light
Physics ⇒ Light and Optics
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 8
A student observes that when sunlight passes through a prism, the emerging light forms a pattern of colors. What is the reason for this observation?
A student shines white light through a prism and observes a band of colors on the wall. What is this band of colors called?
Describe how dispersion of light is different from refraction of light.
Describe what happens to white light as it passes through a glass prism.
Explain why a glass prism is able to disperse white light but a glass slab does not show dispersion clearly.
Explain why a rainbow is an example of dispersion of light.
