6.8 The Doppler formula for the observed frequency f from a source moving with velocity along the line of sight of an observer is where fo is the frequency in the rest frame of the source. (a) What is the distribution in frequency of a partícular spectral line radiated from a gas at temperature T? (b) Find the breadth of the line, de fined as the variance (f -fo)2. (c) Atomic hydrogen and atornic oxygen are...

Q2
(2) Problem 12.6 from Griffiths, Introduction to Electrodynamics, 3rd ed Problem 12.6 from Griffiths, Introduction to Electrodynamics, 4th ed Every two years, more or less, the New York Times publishes an article in which someone claims to have found an object traveling faster than the speed of light. Many of these reports result from a failure to distinguish what is seen from what is observed that is, from a failure to account for light travel time. Here's an example:...

3. a) As shown in Figure 3a, a hibernating astronaut in a ship at rest lies on a recliner making an angle = 35° with the horizontal. The height of the recliner is y = 1.15 meters. In Figure 3b, the ship is moving at velocity v = 0.75c with respect to a stationary observer. Calculate the value of the Lorentz factor y. What is the observed angle e' of the length-contracted recliner? Figure 3b. Relativity: 1 - 22 ť=yto...

Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...

The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...
