A) \[{{60}^{o}}\]
B) \[{{\sin }^{-1}}\left( \frac{8}{9} \right)\]
C) \[\beta =0.\text{1}\]
D) \[{{P}_{1}}\]
Correct Answer: D
Solution :
We know that for total internal reflection, the incident angle must be greater than or equal to the critical angle for which the reflected angle is 90°. Here, \[{{(Kg)}^{1/2}}\] \[{{(Kg)}^{-1/2}}\] \[{{(Kg)}^{2}}\]You need to login to perform this action.
