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 12
A beam of white light passes through a colloidal solution. What phenomenon will you observe?
A laser beam is passed through a smoke-filled room. The path of the beam becomes visible. What is the reason for this observation?
A scientist observes that the sky on a distant planet appears green. Suggest a possible reason based on the scattering of light.
A student observes that the sky is more blue on a clear day than on a hazy day. Explain why.
Calculate the ratio of the intensity of scattered blue light (λ = 450 nm) to red light (λ = 650 nm) using Rayleigh’s law.
Calculate the relative intensity of scattered light for green (λ = 550 nm) and violet (λ = 400 nm) light using Rayleigh’s law.
Describe how the color of the sky would change if Earth’s atmosphere contained larger particles.
Describe the difference between Rayleigh and Mie scattering.
Describe the role of atmospheric dust and pollution in the scattering of light.
Explain why stars appear to twinkle when observed from the Earth’s surface.
Explain why the sky appears black when viewed from the moon’s surface.
Explain why the sky appears blue during the day but reddish-orange during sunrise and sunset.
Explain why the sky appears blue to an observer on Earth but not to an astronaut in space.
Explain why the sun appears white when it is overhead but appears red at sunrise and sunset.
State the mathematical expression for the intensity of Rayleigh scattered light as a function of wavelength.
