Question

Two plain mares are facing each other. They are parallel 3 cm apart and 17 cm in length as the drawing indicates a laserbeam is directed at the top mirror from the left edge of the bottom mirror what is the smallest angle of incident with respect to the top mirror so that the laserbeam hits only one of the mirrors and hits each mirror only once.

Step 1

The laser starts at (0, 0) and hits the top mirror at some point (x1, 3). The angle of incidence with respect to the top surface (horizontal) is α = arctan(Δy/Δx) = arctan(3/x1). Show more…
