Assume that light of wavelength 500 nm is used to illuminate a telescope. What is the resolving power of a telescope whose objective has a radius of 200 cm ?

Text Solution

Verified by Experts

Limit of resolution `Deltatheta~~(0.61lambda)/a`
`Deltatheta~~(0.61xx500xx10^(-9))/(200xx10^(-2))`
`Deltatheta~~1.525xx10^(-7)`
R.P.=`1/(Deltatheta)=6.5xx10^6`
