A slab of transparent materials is made as shown in the figure. Monochromatic parallel beams of light are normally incident on the slabs. The thickness of C is twice the thickness of B. The number of waves is A= the number of waves in the combination of B and C. The refractive index of material A is mu_(0)=1.5 and that of C is mu_(2)=1.4

Consider slabs of three media A,B, and C. Arragned as shown inn figure . R.I of A is 1.5 and that of C is 1.4. If the number of waves in the combination B and C then refractive index of B is
