Scattering of Light
Physics ⇒ Light and Optics
Scattering of Light starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Scattering 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 10

A student observes that the sky appears blue on a clear day but turns whitish on a very humid day. Explain why this happens.
Describe Rayleigh scattering.
Explain why the moon appears red during a lunar eclipse.

True or False: Scattering of light can occur in both solids and liquids.
True or False: Scattering of light is more effective for longer wavelengths.
True or False: The amount of scattering increases as the size of the scattering particles increases.
True or False: The red color of the sunset is due to the scattering of light.
