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.

Describe the difference between constructive and destructive interference.
Describe the effect of increasing the slit width in Young's double slit experiment on the visibility of fringes.
Explain why soap bubbles show different colors when viewed in white light.
Explain why the interference pattern is not observed when the two slits are illuminated by two different lamps.
Explain why soap bubbles show different colors when viewed in white light.
In a double slit experiment, the distance between the slits is 0.2 mm, the screen is 1 m away, and the wavelength of light is 500 nm. Calculate the distance between the first and third bright fringes.
