Question
If a lens suffers from spherical aberration, stopping down willa. worsen the focus.b. improve the focus.c. not affect the focus.
Step 1
Stopping down refers to reducing the aperture size, which in turn reduces the amount of light entering the lens. When you stop down a lens with spherical aberration, you are effectively reducing the amount of light that passes through the outer edges of the lens. Show more…

The aperture of a telescope objective is increased to produce (a) larger image (b) smaller spherical aberration (c) smaller chromatic aberration (d) larger resolving power
In a reflecting astronomical telescope, if the objective (a spherical mirror) is replaced by a parabolic mirror of the same focal length and aperture. Then (a) the final image will be erect (b) larger image will be obtained (c) the telescope will gather more light (d) spherical aberration will be absent
A convex lens forms a real image of a point object placed on its principal axis. If the upper half of the lens is painted black, (a) the image will be shifted upward (b) the image will be shifted downward (c) the intensity of the image will decrease (d) the image will not be shifted
