WebOct 3, 2024 · The angles of incidence and refraction at first face AB are ∠i and ∠r1. The angle of incidence at the second face AC is ∠r2 and the angle of emergence ∠e. δ is the angle between the emergent ray RS and incident ray PQ and is called the angle of deviati on. Here, ∠PQN = i ∠SRN’ = e ∠RQO = r1 ∠QRO = r2 ∠KTS = δ ∴ ∠TQO = i and … WebCritical angle is affected by the refractive index of second medium with respect to the first medium. This in turn depends on: Wavelength: Critical angle increases with increase in wavelength (least for violet). Temperature: Critical angle increases with increase in temperature. formula Relation between refractive index and critical angle
