Draw a schematic ray diagram reflecting telescope showing how rays coming from a distant object are received eye piece- Write its two important advantages over a refracting telescope-

Toppr Admin · Accepted Answer

Advantages of reflecting telescope over a refracting telescope are:
There is no chromatic aberration for reflecting telescope as the objective is a mirror.
Spherical aberration is reduced in the case of reflecting telescopes by using mirror objective in the form of a paraboloid.
