Ray Optics · Refraction
A compound microscope is designed with two symmetric biconvex lenses. The objective lens is cut vertically, creating two identical plano-convex lenses. One of them is used in place of original objective lens. To retain same magnification keeping the object distance unchanged, the tube length has to be :-
- (1)increased two times
- (2)increased times
- (3)decreased two times
- (4)decreased times
