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 11
A student observes that a red solution appears darker when viewed through a longer path length. Explain why.
A student shines a beam of white light through a colored solution and observes that the transmitted light is green. What can be inferred about the absorption of the solution?
Describe how the thickness of a material affects the amount of light absorbed.
Describe the difference between absorption and transmission of light.
Describe what happens to the energy of light that is absorbed by a material.
Explain why a black car heats up more quickly in sunlight than a white car.
A student observes that a red solution appears darker when viewed through a longer path length. Explain why.
A student shines a beam of white light through a colored solution and observes that the transmitted light is green. What can be inferred about the absorption of the solution?
A blue filter absorbs which color of light most strongly? (1) Blue (2) Red (3) Green (4) Yellow
Which law quantitatively describes the decrease in intensity of light as it passes through an absorbing medium? (1) Snell's Law (2) Beer-Lambert Law (3) Planck's Law (4) Huygens' Principle

Which of the following best explains why the sky appears blue during the day? (1) Absorption of blue light by the atmosphere (2) Scattering of blue light by the atmosphere (3) Absorption of red light by the atmosphere (4) Reflection of blue light from the ocean
A material that absorbs all wavelengths of visible light appears ________ to the human eye.
The absorption of light by a material is maximum when the energy of the photons matches the ________ energy levels of the atoms or molecules.
The absorption spectrum of a substance shows the amount of light absorbed at different ________.
The amount of light absorbed by a material depends on its ________ and the wavelength of the incident light.
True or False: A red object appears red because it absorbs red light and reflects all other colors.
True or False: The absorption coefficient of a material is independent of the wavelength of light.
True or False: The absorption of light by a material always results in an increase in temperature.
True or False: The absorption of light can be used to identify substances through their unique absorption spectra.
