WebApr 11, 2024 · Please note: The Relative Refractive Index of the denser medium concerning the rarer medium will be greater than 1. ii) When light travels from a denser to a rarer medium, the angle of incidence is smaller than the angle of refraction. In this case, the light ray bends away from the normal.

WebRecalling the definition of the refractive index n, the equation for ∆ becomes ∆ = h (n S - n F). Because refractive indices are dimensionless, ∆ will be in the same units as h, normally nanome-ters (nm). Note that the difference in path length for the O and E rays has been neglected in this calculation. WebThe angle of incident is provided as 30° and the angle of refraction is 50°. Compute the refractive index of the second medium? Answer: Given parameters. i (Angle of incidence) = 30° and. r (angle of refraction) = 50° The formula for refractive index is articulated as, n = sin i / sin r. n = sin 30 / sin 50. n = 0.5/0.7660. n = 0.6527 dan\u0027s meds
