In bipism experiment, the distance of `20^(th)` bright band from the centre of the interference pattern is 8 mm. The distance of the `30^(th)` bright band is

A

4 mm

B

8 mm

C

12 mm

D

16 mm

Text Solution

Verified by Experts

The correct Answer is:
C
`(x_(30))/(x_(20))=(30beta)/(20 beta)`
`:. X_(30)=(30)/(20)x_(20)=12 mm`
