Question
Inside of optical equipment like cameras and microscopes, there is an aperture. An aperture is a hole through which light passes inside the optical device. The finite size of the aperture puts limits on the quality of image the optical device can produce. Please explain why there is a lower limit to the size of an object that can be seen with a microscope that uses visible light (an optical microscope). This question requires no math. Your answer should be clearly written with complete sentences.
Explanation / Answer
larger the size of aperture, more light passes through so more is intesity of light at image so quality of image is better.
now our eye and any other optical instrument has limit to resolve two objects distinctly. so of distance between objects is smaller than the minimum distance between two objects then both objects will be seen as a single body and cannot distinguish them. thats why there is lower limit to size of objects
