Interference 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 Interference 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
Describe the effect of increasing the wavelength of light on the separation of interference fringes in Young’s experiment.
Describe what is meant by 'coherent sources' in the context of interference.
Explain the difference between constructive and destructive interference.
Explain why monochromatic light is preferred for observing clear interference patterns.
Explain why two independent light bulbs do not produce an observable interference pattern.
If the phase difference between two interfering waves is π/2, what type of interference occurs?
If the two slits in Young’s experiment are illuminated with light of two different wavelengths, what will be observed?
If the two slits in Young’s experiment are illuminated with white light, what will be observed on the screen?
If the wavelength of light used in a double-slit experiment is doubled, what happens to the fringe width?
In a double-slit experiment, if the intensity at the center of the screen is I₀, what will be the intensity at a point where the path difference is λ/2?
In a double-slit experiment, the distance between the central bright fringe and the first dark fringe is 0.5 mm. If the wavelength of light is 500 nm and the distance between the slits is 1 mm, what is the distance from the slits to the screen?
In Young’s double-slit experiment, the distance between the slits is 0.5 mm and the screen is 2 m away. If the wavelength of light used is 600 nm, what is the fringe width?
In Young’s double-slit experiment, the intensity at a point on the screen is zero. What is the phase difference between the two waves arriving at that point?
State the principle of superposition of waves.
