JEE MATHEMATICS MCQ: PAIR OF STRAIGHT LINES

1 Easy

1 of 1

Application +4 | -1

A ray of light travels along the line

2 x-3 y+5=0

and strikes a plane mirror lying along the line

x+y=2

. The equation of the straight line containing the reflected ray is

View answer and explanation

Correct option: B

3 x-2 y+3=0

Option B (

3 x-2 y+3=0

) is correct because it represents the equation of the reflected ray, calculated by finding the intersection point and using the angle of incidence equals angle of reflection principle.
