"A beam of light is sent along the line `x-y=1`
 
 , which after refracting from the x-axis enters the opposite side by
 
  turning through `30^0`
 
 towards the normal at the point of incidence on the x-axis. Then the
 
  equation of the refracted ray is
 
 (a) `(2-sqrt(3))x-y=2+sqrt(3)`
 
 
 
 (b) `(2+sqrt(3))x-y=2+sqrt(3)`
 
 
 
 (c) `(2-sqrt(3))x+y=(2+sqrt(3))`
 
 
 
 (d) `y=(2-sqrt(3))(x-1)`"
