Two convex lenses of same focal length but of aperture A_(1) and (A_(2) lt A_(1)) , are used as the objective lenses in two astronomical telescopes having identical eyepieces. What is the ratio of their resolving power? Which telescope will you prefer and why ? Give reason. |

Answer» SOLUTION :RATIO of resolving power ` = ( A_(1))/( A_(2))` TELESCOPE of aperture `A_(1)` is preferred Reason `:` HIGHER resolving power `//` More light gathering power. |
