A) separate the blue colour part from the red and green colours
B) separate all the three colours from one another
C) not separate the three colours at all
D) separate the red colour part from the green and blue colours
Correct Answer: D
Solution :
For refractive index of a index, \[\mu =\frac{1}{\sin \,{{i}_{c}}}\,=\frac{1}{\sin {{45}^{\text{o}}}}\,=\sqrt{2}\] As, \[{{\mu }_{red}}=1.39,{{\mu }_{green}}=1.44\,\text{and}\,{{\mu }_{blue}}=1.47\] \[\therefore \] \[({{\mu }_{red}}=1.39)<\mu ,{{\mu }_{green}}>\mu ,{{\mu }_{blue}}>\mu \] Thus, only red colour do not suffer total internal reflection.You need to login to perform this action.
