A) 1.4
B) 1.5
C) 1.75
D) 1.33
Correct Answer: B
Solution :
Time taken by light to travel distance x through a medium of refractive index \[\mu \] is \[t=\frac{\mu x}{c}\Rightarrow \frac{{{\mu }_{B}}}{{{\mu }_{A}}}=\frac{{{x}_{A}}}{{{x}_{B}}}=\frac{6}{4}\Rightarrow {{\,}_{A}}{{\mu }_{B}}=\frac{3}{2}=1.5\]You need to login to perform this action.
