A) Wavelength
B) Volume
C) Pressure
D) Area
Correct Answer: D
Solution :
[d] As \[\mu =\frac{Velocity\,of\,light\,in\,vaccum}{Velocity\,of\,light\,in\,medium}\], 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., \[c{{m}^{2}}\], i.e., area.You need to login to perform this action.
