② Let the critical angles of medium 1 and 2 be C 1 and C2, respectively.
Then sinC 1= 1n 1, sinC2= 1n2.
And n 1=cv 1, n2=cv2, then: sinc1= v1c = 2.4×1083×108 = 0.8, sinc2 =
According to mathematical knowledge: tanC 1=43, tanC2=34.
According to geometry knowledge, r1= h1tanc1,r 1=h2tanC2.
Then r1r 2 = h1tanc1h2tanc2 = I have praised it and stepped on it. What's your comment on this answer?
