Answer :

It is essentially based on geometric constructions which allows us to determine the shape of the wavefront anytime., if the shape of the wavefront at earlier is known.

(ii) We know that, energy expression of any wave is,


Now, for refraction, frequency doesn’t change, so energy will also remain constant.


OR


Magnification power,



Multiplying and dividing by I1G1,



(me=magnification of eye piece, mo=magnification of objective)


Now, and



The magnification power can be increased by using an eye piece of less focal length.
