(R ecall that the sum of all the internal angles of a triangle is 180°.) ???? Tries 0/12 2Communication Blocked Send FeeExplanation / Answer
Given; a = 50.2 deg & Incident angle = 46.9 deg
Base angles = (180 – 50.2 )/2
= 64.9 deg
Refraction (Theta R) = 90–64.9
= 25.1 deg
Refractive index= sin(theta I)/sin(theta R)
=sin(46.9) /sin(25.1)
= 1.72
So option F.
