Refractive index mu is given as `mu=A+B/lambda^2,` where A and B are constants and lambda is wavelength, then dimensions of B are same as that ofA. WavelengthB. VolumeC. PressureD. Area |

Answer» Correct Answer - D As `mu = ("Velocity of light in vaccum")/("Velocity of light in medium")`, hence `mu` is dimensionless. Thus , each term on the RHS of given equation should be dimensionless , I,e, `B // lambda^(2)` is dimensionless, i.e., `B` should have dimension of `lambda^(2)`, i.e., `cm^(2)`, i.e., area. |
