A certain X-ray machine generates X-rays from a beam of electrons accelerated from zero to 99.9999999 per cent the speed of light in a long linear accelerator of length 3.2 km. The electrons are generated in pulses of duration ∆t = 100 fs. The generated x-rays from the target are also short pulses (λ = 0.15 nm). What is the average power of the x-ray beam if it pulses 120 times per second and one x-ray pulse contains about a trillion photons (n = 1012).
a) 16.0 W
b) 1.6 W
c) 0.16 W
d) none of these.
A light beam with the wavelength of 660 nm (AA) is created by a spaceship (A), is
observed as its wavelength is 924 nm (Aobserved). Another spaceship (B) is observed by Earth
as it is receding with the speed of 0.7c (VB,Earth). The angular distance between these two
spaceship is 90 degrees for an observer at Earth.
Find the speed of the spaceship B for an observer located at the spaceship A (VBA).
M = 660nm
VB,A = ?
Aobserved = 924nm
VB,Earth = 0.7c

Alice is moving with 0.8c towards a mirror. She sends a light pulse towards the mirror when she is at a distance L from the mirror. Bob is at rest with respect to the mirror and is observing this experiment. After how long will Alice receive the reflected pulse, as measured by Alice and Bob?

At one of the many stop lights he encounters, he gets pulled over for going through a red light. He tries to appeal his ticket. On the day of his trial, he pulls out his physics box of tricks and convinces the judge that he claims the light was actually green (of wavelength 550 nm) and not red (of wavelength 650 nm) because of the relativistic doppler effect. The judge finds this explanation fascinating and lets the physicist go free provided he pay the fine of $1 for every mph he exceeded the speed limit of 35 mph? How much was the fine?arrow_forward
