Webphysics An apparatus used to measure the distribution of the speeds of gas molecules. The device consists of two slotted rotating disks separated by a distance d d, with the slots displaced by the angle \theta θ. Suppose the speed of light is measured by sending a light beam toward the left disk of this apparatus.
