Assume that light of wavelength 600 Å is comingfrom a star. What is the limit of resolution of telescope whose objective has a diameter of 100 inch? |

Answer» SOLUTION :The limit of resolution of a telescope, `dtheta = (1.22lambda)/(D)` `D=100 :"inch"=254CM "" [therefore1"inch"=2.54cm]` `LAMBDA = 6000 Å=6000xx10&^(-10) m` `dtheta = (1.22 xx 6000 xx 10^(-10))/(254 xx 10^(-2)) = 2.9 xx 10^(-7)` `d theta = 2.9 xx 10^(-7) rad` |
