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.

A beam of white light is passed through a prism and a screen is placed to capture the spectrum. If the prism is replaced with a rectangular glass slab, what will be observed on the screen?
A student shines white light through a glass prism and observes a spectrum on the wall. What is the physical explanation for the appearance of different colors?
Describe an experiment to show the recombination of the spectrum of white light.
Describe the process of rainbow formation in the atmosphere.
Explain why a prism causes white light to split into different colors.
Explain why the angular separation between colors in a spectrum increases with the increase in the angle of the prism.
Explain why the colors in a spectrum do not overlap when white light is dispersed by a prism.
Explain why the sky appears blue but the sun appears red during sunset, in terms of dispersion and scattering.
If a prism disperses white light into its constituent colors, what will happen if only red light is passed through the prism?
If the angle of deviation for red light is 38° and for violet light is 40° in a prism, what is the angular width of the spectrum?
If the refractive index of glass for red light is 1.51 and for violet light is 1.53, which color will bend more when passing through a prism?
List the colors of the visible spectrum in order from longest to shortest wavelength.
What is meant by the dispersion of light?
When white light passes through a prism, which color emerges at the top of the spectrum?
Which color of light has the shortest wavelength in the visible spectrum?
Which color of visible light has the longest wavelength?
Which property of light is responsible for dispersion?
