At Kavalur in India, the astronomers using a telescope whose objective had a diameter of one metre started using a telescope of diameter 2.54 ~m . This resulted in
Options
- Athe increase in the resolving power by 2.54 times for the same
- Bthe increase in the limiting angle by 2.54 times for the same
- Cdecrease in the resolving power
- Dno effect on the limiting angle
Correct answer
A. the increase in the resolving power by 2.54 times for the same
Step-by-step solution
Diameter of objective, array ll & D₁= Im , D₂=254 ~m Resolving power, & R_ P = D 1.22 Since, & R_ P D & R_ P₁ R_ P₂ = D₁ D₂ = 1 2.54 & R_ P₂ =2.54 R_ P₁ array
