##### Reference no: EM13518400

You're an optometrist, mounting a projector at the back of your 3.8m -long exam room, 2.6m above the floor. It shines an eye-test pattern on the opposite wall. Patients will sit with their eyes 2.8m from the wall and 1.5m above the floor to view the pattern.

At what height should you center the pattern on the wall?
