Students have asked these similar questions
You want to create a telescope with a resolving powe
of 0.100 arc seconds at a wavelength of 550 nm. Wha
diameter (in m) do you need?
If you want to increase the light gathering power by a
factor of 10, by what factor does the diameter need to
increase?
What would the new resolving power be (in arc
seconds)?
What is the resolving power of a 25-cm (10-in.) telescope at a wavelength of 550 nm (in the
middle of the visual band)?
The James Webb Space Telescope has a primary mirror of diameter ? = 6.5metres. When observing at 1100nm wavelength, calculate the minimum angular separation between two stars which can just be resolved; give your answer in arcseconds (arcsec), where 1 arcsec = 1/3600 degree, to 3 decimal places.
