Light of wavelength 600 nm passes through double slits 0.50 mm apart onto a screen 2.0 m away. What is the fringe spacing?
Answer and explanation
Correct answer: D. 2.4 mm
- Step 1: . Step 2. m. Answer: 2.4 mm. Why not the others: 2.4 micrometres leaves the slit separation in millimetres; 24 mm uses 0.05 mm for the separation; 1.5 x 10^-10 m swaps D and s.
