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 ?
Options
A.0.1 mm
B.0.5 mm
C.0.02 mm
D.0.2 mm
Solution
Angular width of central maxima in double slit
experiment =
Angular width of central maxima in single slit
experiment =
According to the question
⇒ d′ = 0.2 d = 0.2 mm
hence option (4)
experiment =
Angular width of central maxima in single slit
experiment =
According to the question
⇒ d′ = 0.2 d = 0.2 mm
hence option (4)
