At heights of 10 to 30 km above the earth's surface, cosmic rays are continually striking oxygen and nitrogen atoms and producing Ļ mesons, both charged and neutral. follow one of the Ļ+ mesons on its way down. observer b is in the reference frame attached to the particle ( rocket frame ) and determines the average life of the meson to be 2 55 Ć 10-8s. suppose that the rocket frame moves at a speed u = 12c/13 relative to the earth's reference frame, and that observer a at rest in the earth's frame determines the average lifetime of the Ļ-meson to be 6.63 Ć 10-8s. (a) how far does the Ļ-meson move in the laboratory frame between its birth and decay ? (b) according to observer b how far does the particle move between birth and decay in the laboratory frame? note: you may ignore the effects of gravity on the particle motion which you should treat accong to chunics.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
