8. A prism of unknown material is in air (n=1.00). Total internal reflection begins (critical angle) when light within the prism reaches a surface at an angle (relative to normal) of 0 54.4°. What is the refractive index of the prism? (If question is ambiguous, explain.)) air n=?

using the Hubble telescope, which has diameter D 2.4 meters. Assume the telescope's
resolution is only limited by diffraction, and use visible light with wavelength à 480 nm
(4.8x10'm). Use the small angle approximation: tan 0= sin 0= 0.
a. What is the smallest angle that Hubble could resolve (diffraction limit), in radians?
