For iage to be coincident, either the rays should retrace or the iage due to the lens should fored just at the pole of the irror in thin case. The iage fored due to lens is at c (f) be fro the lens. Thus either this iage should be at centre of curvature of the convex irror or at the pole of the irror. Hence 6c or c should be the separation between the lens and the irror. 6. no of fringes shifted.48 48 6 x t 7. frequency of vibration of wire will be equal to the frequency of the source hence f = 4Hz 8.
