A ray of light travelling along the line x+y = 1 line incident on the x-axis and after rrefraction it enters the other side of the x-axis by turing pi//6 away from the x-axis. The equation of the line along which the refracted ray travels is

Answer»

`X+(2-sqrt3)y=1`
`(2-sqrt3)x+y=1`
`y+(2+sqrt3)x=2+sqrt3`
`y+(2-sqrt3)x=2-sqrt3`
