Electromagnetic radiation from a star is observed with an earth-based telescope. The star is moving away from the earth with a speed of 0.570c.
If the radiation has a frequency of 8.64×1014Hz in the rest frame of the star, what is the frequency measured by an observer on earth?
Express your answer with the appropriate units.

Light radiates from a distant star that is moving towards Earth. In the Earth's frame of reference the light has a wavelength of 400 nm. If the star is moving with a speed of 0.41 c, what wavelength, in nm, will be seen by an observer in the star's frame. Calculated your answer to two decimal places.

The spaceship Enterprise 1 is moving directly away from earth at a velocity that an earth-based observer measures to be +0.69c. A sister ship, Enterprise 2, is ahead of Enterprise 1 and is also moving directly away from earth along the same line. The veolcity of Enterprise 2 relative to Enterprise 1 is +0.45c. What is the velocity of Enterprise 2, (in terms of c) as measured by the earth-based observer?

One of the primary goals of the Kepler space telescope is to search for Earth-like planets. Data gathered by the telescope indicates the existence of one such planet named Boralis orbiting a star 120 ly from our solar system. Consider an interstellar spaceship leaving Earth to travel to Boralis. The ship can reach 0.70c almost instantly and can also decelerate almost instantly. The ship is 175 m long in its reference frame. (a) What is the length of the moving...
