If angle of incidence is 30° then angle of refraction and angle of emergence is |
|
Answer» that REFRACTIVE INDEX is the ratio if sines of angle of incidence to angle of refraction. That is,Refractive Index = Sin i / Sin rSo given that, Refractive Index is √3 and sin r is 30°=> √3 = Sin i / Sin 30=> √3 * Sin 30 = Sin i=> √3 * 1 / 2 = Sin i=> Sin i = √3 / 2We know that, Sin 60 is √3 / 2. Hence,Sin i = Sin 60 => i = 60°Hence the angle of incidence is 60°.Hope my answer helped |
