When two plane mirrors are perpendicular to each other and a ray of light suffers reflection from both mirrors, the resulting ray will be perpendicular to the original ray.

Here's the step by step explanation:

1. The ray of light hits the first mirror at an angle. Because the angle of incidence equals the angle of reflection, the ray of light is reflected off the first mirror at the same angle.

2. This reflected ray then hits the second mirror, which is perpendicular to the first. Again, the angle of incidence equals the angle of reflection, so the ray of light is reflected off the second mirror at the same angle.

3. Because the two mirrors are perpendicular to each other, the total change in direction of the ray of light after reflecting off both mirrors is 90 degrees. Therefore, the resulting ray is perpendicular to the original ray.
