One is made of material A with a refractive index of 1.5. The other is made of two materials B and C with thickness in the ratio 1:2. The refractive index of C is 1.6. If a monochromatic parallel beam passing through the slabs has the same number of wavelengths inside both, the refractive index of B is | Physics | Refraction at a plane surface | JEE Adv |
