Question

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

Answer 1

θ=0.0288 radian

Step-by-step explanation:

resolution limit is the minimum angular separation of two sources that can be viewed distinctly by telescope

`\theta =(1.22* \lambda)/(D)`

`\lambda=6000* 10^(-8) cm=6 * 10^(-5) cm`

`d=100 inch=100* 2.54=254cm`

`\theta = (1.22 * 6 * 10^(-5))/(254)`

θ=0.0288 radian
