Suppose refractive index is given as =A+ B ² , where A and B are constants and is wavelength, then dimensions of B are same as that of
Options
- Awavelength
- Bvolume
- Cpressure
- Darea
Correct answer
D. area
Step-by-step solution
Refractive index, =A+ B ² According to principle of homogeneity, Dimension of B ² = Dimension of aligned [B] &=[ ] [ ² ] &= [ M ⁰ ~L ⁰ ~T ⁰ ] [ L ² ] &= [ L ² &= Dimension of area aligned
