Q. Find angle of re fraction45n=1n=√2 |
|
Answer» efractive index of first medium, n₁= 1Refractive index of second medium, n₂ = √2Angle of INCIDENCE, i= 45°To Find:Angle of refractionSolution:We know that,ACCORDING to Snell's Lawwhere,i is angle of incidencer is angle of refractionμ₁ is REFRACTIVE index of medium where incident ray is presentμ₂ is refractive index of medium where refracted ray is presentLet the angle of refraction be rOn USING Snell's LAW ,we getHence, the angle of refraction is 30°. |
