Explain the following:(a)For a simple microscope, the angular size of the object equals the angular size of the image. Yet it offers magnification.(b)Both plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances?
Explain the following:
(a)
For a simple microscope, the angular size of the object equals the angular size of the image. Yet it offers magnification.
(b)
Both plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances?
Marking-scheme solution
(a)
Yes, it offers magnification.
We can keep the small object much closer to the eye than $\displaystyle 25$ cm and hence have it subtend a large angle.
(b)
Yes,
Rays converging to a point behind a plane or convex mirror are reflected to a point in front of the mirror on a screen
