Which mechanism creates standing waves within lidar scanning cavity?

💡 Explanation

Constructive interference causes standing waves within the cavity because incident and reflected light waves superimpose in phase, therefore amplifying intensity at resonant frequencies, rather than refraction or pulse manipulation which involve beam direction and phase shifts.
