Effect of increasing diameter of objective of comp microscope on magnifying power
Answers
it is raining! You want to collect as much water as possible. Your bucket isn’t big enough. Besides, only a small amount of water falls in your narrow bucket.
What do you do?
Bring a wider bucket? Hell, a tub!
The aperture of the telescope works the same way. A larger aperture only serves to increase the area onto which the light falls, thereby increasing the brightness of the object and hence forming a sharper, more defined image.
Theoretically, the magnifying power does not depend on aperture at all.
BUT
Larger aperture allows higher magnifications as higher magnifications require more light to create a bright-enough image.
Conversely, if I have a small aperture, and even if I am able to magnify to a certain value, I might not be able to comprehend the dim and poor-contrast image (even though the magnification is exactly the same as larger aperture one).
So, larger aperture does rock! Except it is expensive, and bulky.
