Two mirrors are placed perpendicular to each other. A beam of light reflects off mirror 1 with incident angle θi = 78 degrees, then reflects off mirror 2 with angle θf.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
