Qw The Hubble telescope has a primary mirror with diameter 2.4 m. Calculate the angular resolution of the Hubble telescope in both radians and degrees at a wavelength of 600 nm. Imagine that the Hubble telescope images the surface of the moon, 3.84*10^8 m away. What is the smallest feature on the surface of the moon that the telescope can resolve at a wavelength of 600 nm?
How do you solve for the second part of this question. thanks in advance

The definition of an angle is???? If you know the angular resolution, an object that subtends the resolution angle is the smallest thing that can be resolved.
