Answer #1

Wavelength () = 0.2 microns = metre = 0.0000002 m

Numerical aperture (NA) = 1.6

Smallest distinguishable distance (d) =

= 0.61 * 0.0000002 / 1.6

= m

= 76.25 nanometre

Resolving power = 1/d = 1.31 x 10^7

The Hubble Space Telescope (HST) has excellent resolving power because there is no atmospheric distortion of the light. Its 2.40 m diameter primary mirror can collect light from distant galaxies that formed early in the history of the universe. How far apart can two star clusters be from each other if they are 21.2 billion lightyears away from Earth and are barely resolved by the HST using visible light with a wavelength of 414 nm?
