A laser source, situated at a distance $$d$$ from a plane wall $$P$$, rotates around an axis $$E$$, with constant angular velocity $$\omega$$, emitting a laser beam marks a red spot that moves in a straight line along the wall. The red spot has an instantaneous velocity $$v$$. The picture represents a view from above. Find $$v$$ in terms of $$\omega$$, $$d$$ and the angle $$\theta$$.
