In Young's experiment with a monochromatic light of wavelength 5890 Å , the slits are separated by a distance 1 mm. Find the angular width between two successive interference fringes.

Text Solution

Verified by Experts

Here `lambda` =5890 Å =5890 `xx 0^(-8)` cm and 2d = 1 mm =0.1 cm.
Angular widht between two successive bright or dark bands ,
`theta =(lambda)/(2d) =(5890 xx 10^(-8))/(0.1)` radian
`= 5890 xx 10^(-7) xx (180)/(pi)` degree = 0.03 degree
