# A ray of light is sent along the line x+y=1 after being reflected from the line y_x=1 it is again reflected from the line y=0 then the equation of the line representing the ray after second reflection may be given as?

##### 1 Answer

#### Answer

#### Answer:

#### Explanation

#### Explanation:

Here, is a diagram of the whole thing happening,

Light after coming by the pathway of

Now, clearly, slope of the straight line

So,let the equation of the reflected pathway is

And, that of the straight line,to which it will be parallel is

Now,if the distance between them is

here,

So,

So,the equation of straight line,alomg which the reflected ray will go, will be
