Absorption of Light
Physics ⇒ Light and Optics
Absorption 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 Absorption 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 measures the temperature of two objects, one black and one white, after placing them in sunlight for 10 minutes. The black object is hotter. What does this demonstrate about absorption of light?
A student observes that a red filter absorbs all colors except red. What color will a white light appear after passing through the red filter?
A student shines white light on a blue object in a dark room. What color will the object appear?
Describe what happens to the energy of light when it is absorbed by a material.
