Two slits are made 1 mm apart and the screen is placed 1 m away. What is the fringe width when a light used of wavelength 500 nm? |
5 mm 1 mm 0.25 mm 0.5 mm |
0.5 mm |
The correct answer is Option (4) → 0.5 mm In young's double slit experiment, $β=\frac{λL}{D}$ $=\frac{500×10^{-9}×1}{1×10^{-3}}=0.5mm$ |
