Why do optical astronomers put their telescopes on the tops of high mountains, while radio astronomers put their telescopes in deep valleys.
Explain what the fine structure constant tells us about the relative probability of the formation of a three particle event (muon antimuon and photon).
In the old west, a marshal riding on a train traveling 50m/s sees a duel between two men standing on the earth 50m apart parallel to the train.
Where W is either magnetic B or electric E field vector, show that by using Galilean transformation wave equation will be changed to.
What is the angular speed of the antenna as measured by an observer moving away from the antenna with a speed of 0.62c?
According to an observer on the Earth, ship A is moving at a speed of 0.753c and ship B at a speed of 0.851c.
Show that the spacetime interval (delta s) is invariant under the lorentz transfermations:c= speed of light in a vacuum ; 's indicate a different system.
Use the Lorentz transformations to show that the spacetime interval is invariant, ?s'2 =?s2 for relative motion along one direction.
A pion of mass m moves with a speed u in the positive y direction in frame S with parametrs BETAu = u/c and GAMMAu = (1 - BETAu^2)^-1/2.
Given that both systems contain two mass-m particles with K=5m, explain any difference between your answers to parts (a) and (b).
Find expressions for the energies E1 and E2 in terms of the electron mass, the speed (beta) and angle theta(1).
If the Oh-My-God particle were subjected to a uniform magnetic field of B = 1 [T], what would be the radius of particle's trajectory?
How does the behavior of the light beam differ from the behavior of a bullet fired in the same direction from the top of the freight car?
Derive the equation that would allow you to calculate the speed of the electrons from the accelerating potential.
A set of quantities , whose inner product with an arbitrary vector (that is, a contravariant tensor of rank one) is a tensor.
The momentum of B relative to O is p=mv according to Newtonian mechanics and p=gammaxmv according to Special Relativity.
Determine the radial distance between the two clocks. Compare your result to what it would be if the space surrounding this mass were flat.
Suppose you sing or yell into an open piano with its dampers lifted off the strings. You are likely to hear the instrument "speak" back in response.
A student in a parked car honks the horn, which has a `proper' frequency of 300 Hz. An observer in an approaching vehicle measures the frequency of the sound.
Where will the plane be when it is finally heard?(Assume an average value of 330m/s for speed of sound in air).
John and Sue are descending on ropes into a cave. Sue's rope breaks and she falls screaming past John. Apply doppler effect.
Two automobiles are equipped with the same single frequency horn. When one is at rest and the other is moving toward an observer at 15.9m/s.
Ultrasound reflected from an oncoming bloodstream that is moving at a 30 cm/s is mixed with the original frequency of 2.5 MHz.
What is the observed frequency if the observer moves away from the source instead?
What frequency do you detect if you move with a speed of 30.0m/s (a) toward the car, and (b) away from the car?
