उत्तर
If `"^imu_j` represents refractive index, when a light ray goes from medium i to medium j, then the product `"^2mu_1 xx ^3mu_2 xx ^4mu_3` is equal to `underline("^4mu_1)`.
Explanation:
When refraction takes place through a multiple media, we have
`""^amu_c = ""^amu_b xx ^bmu_c`
`therefore ""^2mu_1 xx ^3mu_2 xx ^4mu_3 = "^4mu_1`
