✔ 最佳答案
Refractive index for light to travel from medium 1 to medium 2= 1.6/1.33 = 1.203
Let c be the critical angle (臨界角),
hence sin(c) = 1/1.203 = 0.8313
c = arc-sin(0.8313) = 56.23 degrees

臨界角的式:
C=sin-1(物質1/物質2)
它們之間邊界的臨界角:
sin-1(1.33/1.6)
=56.2273..........
C=sin-1(物質1/物質2)
它們之間邊界的臨界角:
sin-1(1.33/1.6)
=56.2273..........

n1sinθ1 = n2sinθ2
光從物質2進入物質1(折射率大-->折射率細)才會出現全內反射
1.6 sinC = 1.33sin90°
sinC = 1.33/1.6
C = 56.2°
光從物質2進入物質1(折射率大-->折射率細)才會出現全內反射
1.6 sinC = 1.33sin90°
sinC = 1.33/1.6
