What will be the angular width of central maxima in Fraunhofer diffraction when light of wavelength `6000Å` is used and slit width is `12xx10^-5cm`?

A

3 rad

B

8 rad

C

2 rad

D

1 rad

Text Solution

Verified by Experts

The correct Answer is:
D
`omega_(0) = (2lambda)/a`
`omega_(0) = (2 xx 6000 xx 10^(-10) (m))/(12 xx 10^(-7) (m))`
`omega_(0) = 1` rad.
