A) wavelength
B) pressure
C) area
D) volume
Correct Answer: C
Solution :
We know that energy equation relating physical quantity should be in dimensional balance. Hence, dimensions of terms on both sides of given equation must be same. Given, \[\mu =A+\frac{B}{{{\lambda }^{2}}}\] where refractive index is a dimensionless quantity, hence \[\frac{B}{{{\lambda }^{2}}}\] is also dimensionless \[\therefore \] Dimension of B = dimension of \[{{\lambda }^{2}}\] \[=c{{m}^{2}}\] = dimensions of areaYou need to login to perform this action.
