Answer:
2.46
Explanation:
From the question given above, the following data were obtained:
Critical angle (C) = 24 °
Refractive index (n) =?
The refractive index of the diamond can be obtained by using the following formula as illustrated below:
Refractive index (n) = 1 / sine [critical angle (C)]
n = 1/sine C
n = 1 / sine 24 °
n = 1/0.4067
n = 2.46
Thus, the refractive index of the diamond is 2.46
