From vector diagrams to real collision experiments, momentum labs bring physics concepts into focus. Students connect theory with practice by designing and analyzing their own setups. These activities ...

A pulling force can be generated via amplification of the photon linear momentum when a fairly uniform light field passes from one dielectric to another with a higher refractive index. This force can ...

The fact that light carries both linear and angular momentum is well-known to physicists. One application of the linear momentum of light is for optical tweezers, in which the refraction of a laser ...
