A double slit is illuminated by light of wavelength 6000 Å. The slits are 0.1 cm apart and the screen is placed one metre away. calculate :
The angular position of the 10th maximum in radians and

Explanation

`lamda=6000A=6times10^-7m,d=0.1cm=1times10^-3m D=1m,n=10`
Angular position `theta_n=(nlamda)/d=(10times6times10^-7)/10^-3`
`=6times10^-3 rad`
