If the refractive index of second medium with respect to first medium is 2n1 and that of third medium with respect to second medium is 3n2, what and how much is 3n1? |
---|
→ 3n1 means the refractive index of the third medium with respect to the first medium. Here, 2n1 = \(v_1\over v_2\), 3n2 = \(v_2\over v_3\) ∴ 3n1 = \(v_1\over v_3\) = \(v_1\over v_2\) × \(v_2\over v_3\) ∴ 3n1 = 2n1 × 3n2 2 Marks |
