Homework Statement
What apeture is required to give 1-arcsec resolution for a wavelength of 500 nm(visible)
Homework Equations
theta=wavelength/d ; d is the size of the apeture
The Attempt at a Solution
I'm assuming when they are asking for the apeture , they are asking for the size of the apeture.
theta=wavelength/d => d=wavelength/theta =
I converted 1 arc second to 5*10^-6 radian
d=500*10^-9 m/5*10^-6= .1 m
