... Suppose a wave pulse is initiated at the positive-x end of a stretched rope and travels in the −x direction toward x = 0. We'll call this the incident pulse. Now suppose the point x = 0 is held stationary by a clamp, so that for any time t, y(0, t) = 0. What happens? Observation shows that a second ...

Introduction to Nuclear and Particle Detectors
... Matter - Summary When particles pass through matter they usually produce either free electric charges (ionization) or light (photoemission). How can we use this? Most “particle” detectors actually detect the light or the charge that a particle leaves behind. In all cases we finally need an e ...
