Notes from the JEE Toppers
6 : Young’s Double Slit Experiment
- Know the conditions for constructive and destructive interference.
- Calculate the fringe width using the formula $$(w = \frac{\lambda D}{d}),$$ where (w) is the fringe width, λ is the wavelength of light, (D) is the distance to the screen, and (d) is the separation between the slits.
