1 Pts A Group Of Pions Is Observed Traveling At Speed 0 9c In A Particle Physics Accelerator The Proper Half Life 1 (7.81 KiB) Viewed 453 times
A) A green LED (l = 500 nm) flashes on a piece of a pion
detector located at the distance of 50
meters in the laboratory. What is the wavelength of this light
according to the pion?
B) Suppose that the pion emits an 85 MeV photon and then a 50
MeV photon. What is the speed of
the pion after emitting both photons? (Mp = 140 MeV/c2)
1. (?? pts) A group of pions is observed traveling at speed 0.9c in a particle physics accelerator. The proper half-life of the pions is 1.8x10-8 s.
