A thin slice is cut out of a glass cylinder along a plane parallel to its axis. The slice is placed on a flat glass plate as shown in Figure. The observed interference fringes from this combination shall be

A

straight

B

circular

C

equally spaced

D

having fringe spacing which increases as we go outward

Text Solution

Verified by Experts

The correct Answer is:
a
Locus of equal thickness are lines running parallel to the axis of the cylineder. Hence straight fringe will be observed.
