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?
Calculate the absorbance if the incident light intensity is 100 units and the transmitted intensity is 10 units. (Use the formula: Absorbance = log10(I0/I))
Describe what happens to the energy of light when it is absorbed by a material.
Explain why a red flower appears black under green light.
Explain why black surfaces become hotter than white surfaces when exposed to sunlight.
Explain why plants look green in sunlight.
Explain why sunglasses are often tinted dark colors.
If a material absorbs 80% of the incident light, what percentage of light is transmitted or reflected?
If a material absorbs all wavelengths of visible light, what color does it appear to the human eye?
If a material has a high absorption coefficient, what does this mean?
State the relationship between the color of an object and the wavelengths of light it absorbs.
What happens to the intensity of light as it passes through an absorbing medium?
What is meant by the absorption of light?
What is the main difference between absorption and reflection of light?
