The diameter of the objective of a telescope is 1.2m. Ig the wavelength of light used is 546 nm, then calculate the limit of resolution of the telescope.

Text Solution

Verified by Experts

Given `D=1.2m , lambda=546xx10^(-9) m `
Limit of resolution,
`d.theta=(1.22 lambda)/(d)`
i.e., `d theta=(1.22xx546xx10^(-9))/(1.2)=5.551xx10^(-7)` rad
