1. Standard Physics Teaching Bench
Physics Teaching AssistantBackground
A university laboratory uses green 550 nm light with 0.2 mm slits positioned 2 meters from the projection screen.
Problem
Calculate theoretical fringe separation to verify that students can resolve bands with standard rulers.
How to use
Enter 550 for wavelength (nm), 200 for slit separation (µm), and 2 for screen distance (m).
λ = 550 nm, d = 200 µm, L = 2 mOutcome
Generates a fringe spacing of Δy = 5.50 mm, an angle θ₁ = 0.157564°, and fringe offsets up to ±22.00 mm for m = 4.
