a ray of light has an equation x + y =1. If the angles between the incident ray and normal and the reflected ray and normal are equal, then find the equation of the reflected ray.

Question

anonymous · Answer

y=-x+1
then -1 is the slop
angle is tan inverse of -1 which is 135
hence the angle between the indecent ray and  the normal is 45 degree  
hence the angle between the reflected ray and  the normal is  also 45 degree 
now try solving
