NEET 2015 Physics question
In a double slit experiment, the two slits are 1 mm apart and the screen is placed 1 m away. A monochromatic light of wavelength 500 nm is used. What will be the width of each slit for obtaining ten maxima of double slit within the central maxima of single slit pattern ?
Answer: (4)
Solution
Let the slit separation be and the slit width be . The fringe width of the double-slit pattern is . The width of the central maximum of the single-slit pattern is
