WebFeb 20, 2024 · Figure 2.3. 3: During a 30-minute round trip to the store, the total distance traveled is 6 km. The average speed is 12 km/h. The displacement for the round trip is zero, since there was no net change in position. Thus the average velocity is zero. Another way of visualizing the motion of an object is to use a graph. WebMar 14, 2024 · Most of the time, a reflection needs no explanation. The collision of light with the mirror's surface is almost intuitive, its rays set on a new path through space with the same ease as a ball bouncing off a wall. For over sixty years, however, physicists have considered a subtly different kind of reflection. hinch hockey

WebThis group delay will in turn be related to the skin depth of the reflecting surface. For a metal say at optical frequencies, the skin depth will be on the order of several nanometers, and so the group delay will be on the order of 10 -17 seconds. This reflection time will be much smaller then the uncertainty in the photon's time of arrival.
