Assume that light of wavelength 6000Å is coming from a star. What is the limit of resolution of a telescope whose objective has a diameter of 100 inch?

here D = 100in = 2.54m

lambda =6000 angstrom= 6 * 10-10 m

putting the formula, 1/theta = D/1.22lambda

We get theta nearly equals to 2.9 * 10-7 radians.

Limit of resolution =delta theta =1/theta =(D in m) /{1.22 *(lambda in m) } =2.54 /(1.22 *6 *10 ^-10) =2.9 *10 ^-7 radians (Ans)
