Two slits separated by 0.33mm.A beam of `500nm` light strikes the slits producing an interference pattern.Tegh number of maxiam observed in the angular angle range`-30^(@)ltthetalt30^(@)`

A

`300`

B

`150`

C

`599`

D

`149`

Text Solution

Verified by Experts

The correct Answer is:
C
`d sintheta-nlambda`
`n=(3xx10^(-4)xxsin30^(@))/(5xx10^(-7)) rArr n=300`
since-`30^(@)lttheta lt 30^(@)`
total number of maximum=`(600-2+1)=599`
