Question

11.41 stead bject (5) The diameter of mirror is large. So the resolving power and magnifying power of reflecting telescope is more. IMPORTANT FACT 1. arge vide nce. the be ght To her ght & ror ed. ain 2. The ability to receive the light in an astronomical telescope depends upon area of objective. If the diameter of objective is more then faint cellestial object can be observed. The resolving power or ability to see clearly two close objects also depends upon diameter of objective. The spherical aberration in a lens is that defect corresponding to which paraxial parallel rays and in marginal parallel rays after refraction do not focus at Due to this defect image is 3.​
