The beam emerges from the laser at a point that is 1.10 m, Ask an Expert

Academics

The drawing shows a laser beam shining on a plane mirror that is perpendicular to the floor. The beam's angle of incident is θ = 32.0°.

The beam emerges from the laser at a point that is 1.10 m from the mirror and 1.80 m above the floor. After the reflection, how far from the base of the mirror does the beam strike the floor?
