(Solution) - In a double slit interference experiment the slit separation -(2025 Original AI-Free Solution)

Paper Details

In a double-slit interference experiment, the slit separation is 2.00?m, the light wavelength is 500 nm, and the separation between the slits and the screen is 4.00 m.
(a) What is the angle between the center and the third side bright fringe? If we decrease the light frequency to 90.0% of its initial value,
(b) Does the third side bright fringe move along the screen toward or away from the pattern's center and
(c) How far does it move?
