- The light from a heated atomic gas is shifted in frequency because of the random thermal motion of light-emitting atoms toward or away from an observer. Estimate the fractional Doppler shift (f/f0), assuming that light of frequency f0 is emitted in the rest frame of each atom, that the light-emitting atoms are iron atoms in a star at temperature 6000 K, and that the atoms are moving relative to an observer with the mean speed =8kBTm Must we use the relativistic Doppler shift formulas f=f01/c1/c for this calculation? Such thermal Doppler shifts are measurable and are used to determine stellar surface temperatures.arrow_forwardTwo spaceships, each 100 m long when measured at rest, travel toward each other with speeds of 0.85c relative to Earth.• How long is each ship as measured by someone on Earth?• How fast is each ship traveling as measured by an observer on the other?• How long is one ship when measured by an observer on the other?arrow_forwardTwo spaceships, each 100 m long when measured at rest, travel towardeach other with speeds of 0.85c relative to Earth. • How long is each ship as measured by someone on Earth?• How fast is each ship traveling as measured by an observer on the other?• How long is one ship when measured by an observer on the other?• At time t0 on Earth, the fronts of the ships are together as they just begin to pass each other.

- special relativity • A) Find the value of y for the following situation. An astronaut measures the length of her spaceship to be 25.0 m, while an Earth- bound observer measures it to be 100 m. (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent? • Solution (a) y = 0.250. (b)It is unreasonable because the value of y is less than one. This opposed the idea of length contraction. © It will give imaginary value.

- As seen below, a muon is travelling in the upper atmosphere. 2.01 km 0.627 km (a) On the left (a) is your reference frame, where you see the muon travelling 2.01 km before colliding with another particle in the adjacent cloud. On the right (b), the muon sees the adjacent cloud travelling 0.627 km before colliding with it. (b) How long does it take for the muon to go from cloud to cloud in each reference frame? Hint: first you'll want to find the velocity v!arrow_forwardEinstein contradicted classical Galilean relativity when he proposed that the speed of light in a vacuum Depends on the relative motion of the observer Is the same for all observers in any inertial frame of reference Can be determined by adding the velocity vectors of light and the motion of the observer Slows down as an observer moves away from the light sourcearrow_forward2. An alternative derivation of the mass-energy formula E, = moc² also given by Einstein, is based on the principle that the location of the center of mass (CM) of an isolated system cannot be changed by any process that occurs inside the system. The Figure below shows a rigid box of length L that rests on a frictionless surface; the mass M of the box is equally divided between its two ends. A burst of electromagnetic radiation of energy E, is emitted by one end of the box. According to classical physics, the radiation has the momentum p = "0%c , and when it is emitted, the box recoils with the speed v z Eo/ so that the total momentum of Mc the system remains zero. After a time t z L/c the radiation reaches the other end of the box and is absorbed there, which brings the box to a stop after having moved the distance S. If the CM of the box is to remain in its original place, the radiation must have transferred mass from one end to the other. Show that this amount of mass is m, = c2.arrow_forward
