The XY plane is the boundary between two tranparednt media. Medium 1 with `z ge 0` has a refraxtive index of `sqrt2` and medium 2 with `z le 0` has a refractive index of `sqrt3`. A ray of light in medium 1 given by the vector `6sqrt(3)hat(i)+8sqrt(3)hat(j)-10hatk` is incident on teh plane of separation. Find the unit vector in the direction of teh refracted ray in medium 2.A. `60^(@)`B. `75^(@)`C. `30^(@)`D. `45^(@)` |

Answer» Correct Answer - 4 Normal to the plane is z-axis `costheta_(1)=(A_(z))/(A)=(10)/(20)=(1)/(2),theta_(1)=60` `mu_(1)Sintheta_(1) rArr mu_(2) sintheta_(2) rArr sqrt(2)xx(sqrt(3))/(2)=sqrt(3)sintheta_(2) rArr theta_(2)=45^(@)` |
