galileo.phys.virginia.edulight travels 300 m. In that time it should fall a distance y = 1/2gt2 = 5*10-12 m, much too small to be seen. Many known properties of light could be explained easily by a particle model. For example it was known that when light reflects from a smooth surface, the angle of incidence is equal to the angle of reflection.

In this manner, lidar is analogous to radar (radio detecting and ranging), except that it is based on discrete pulses of laser light. The three-dimensional coordinates (e.g., x,y,z ...
