Ray box, simple, safe and sturdy source of projected light for many classic optics experiments, produces parallel convergent rays across a plane horizontal surface and the rays are intense enough to be traced in natural light. Built in solid aluminum extrusion casing, 100-240V 50/60 Hz
Time of Flight Pad sensor to precisely measure how long a projectile has been in motion, determine the launch speed of a projectile, along with the time the projectile is in flight, allow students to see just how kinematic calculations work in rea
