Diffraction of Light starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Diffraction 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

Describe the difference between interference and diffraction.
Describe the effect of using white light instead of monochromatic light in a single slit diffraction experiment.
Explain why a telescope with a larger aperture can resolve finer details.
Explain why diffraction effects are not significant in daily life for visible light.
