Optics Physics about mirror resolution?

1. The Hubble Space Telescope (still operational) has a mirror with a diameter of 2.4 m. What 
is the maximum resolution of Hubble when observing Mars at closest approach? The last 
time Mars was closest to Earth, in May of 2016, it was 7.53×1010 m away. And since Mars 
is mostly red, assume the light is reddish, with a wavelength of 630 nm. Could Hubble 
resolve the Endeavor crater on Mars? Endeavor crater is 22 km in diameter. 

2. Calculate the angle of incidence at which light reflecting off of crown glass (with an index 
of refraction of n = 1.86) will have the reflected light completely polarized (Brewster’s 
angle). Then calculate the angle of refraction for this angle of incidence, and verify that 
the reflected and refracted beams are perpendicular.
