Challenge Problems
Push your limits with challenges.
Question 1
In an experiment, if the distance between slits is halved while keeping the distance to the screen the same, how will the fringe width change?
💡 Hint: Think about how changes in d modify fringe spacing.
Question 2
If the wavelength of light is increased while keeping D and d constant, what happens to the interference pattern?
💡 Hint: Consider the relationship between wavelength and fringe width.
