(i)Explain the statement: “Angular magnification of a compound microscope in normal use is 30”.

(ii) State how the resolving power of an astronomical telescope can be increased.

Solution

(i) Angular magnification of a compound microscope in normal use is 30 means that it can magnify the size of the object 30 times.

(ii) By using the Object lens of large aperture in astronomical telescope larger the aperture of the objective lens, smaller the limit of resolution, or greater the resolving power of the telescope.
