The refractive index denser medium with respect to rarer medium is 1.125 The difference between the velocities of light in the two media is `0.25times10^(8)m/s`.Find the velocities of light in the two media and their refractive indices `c=3times10^(8)m/s`

Options

A. `2.0xx10^(0)8m//s,2.25xx10^(8)m//s`,1.500,1.333
B. `2.5xx10^(0)8m//s,2.25xx10^(8)m//s`,1.500,1.333
C. `2.0xx10^(0)8m//s,2.25xx10^(8)m//s`,1.333,1.500
D. `2.5xx10^(0)8m//s,2.0xx10^(8)m//s`,1.500,1.333

Answer

A

Explanation

`mu prop 1/(vel)` and `V_(r)-V_(d)=0.25xx10^(8)ms^(-1)`
