Consider a spiral galaxy that is moving directly away from Earth with a speed V=3.24*10^5 at its center. The galaxy is also rotating about its center such that points in the spiral arms are moving with a soeed V=5.750*10^5m/s relative to the center. If light with a frequency of 7.308*10^14Hz is emitted in both arms of the galaxy, what frequency is detected by astronomers observing the arm that is moving (a) toward and (b) away from Earth? Please break down...

Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 75.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= __________ m/s

According to Hubble's Law the velocity v of a galaxy moving away from Earth is proportional to its distance from Earth. Consider two galaxies one of which is twice as far away as the other from Earth at some instant of time (i.e. the ratio of their distances from Earth is 2 to 1). At subsequent times the ratio of their distances to Earth will be:

Light and the Electromagnetic Spectrum Examples 1) The distance from the Sun to Earth is 1.50 x 1011 m. How long does it take for light to cover this distance? 2) Suppose a particular galaxy emits orange light with a frequency of 5.000 x 1024 Hz. If the galaxy is moving away from Earth with a speed of 3325 km/s, what is the frequency of the light when it is observed on Earth?

An astronomer observed electromagnetic waves emitted by oxygen atoms in a distant galaxy moving toward Earth at a speed of 2.467 times 10^7 m/s. In the laboratory on Earth, oxygen atoms emit waves that have a frequency of 5.841 times 10^14 Hz. At what frequency does the astronomer observe the light emitted by oxygen atoms from the distant galaxy? A certain metal has a work function for photoelectric emission of phi delta = 3.50 eV. What is the threshold frequency...

A distant galaxy is simultaneously rotating and receding from the earth. As the drawing shows, the galactic center is receding from the earth at a relative speed of UG = 1.70 x 106 m/s. Relative to the center, the tangential speed is vT = 5.00 105 m/s for locations A and B, which are equidistant from the center. When the frequencies of the light coming from regions A and B are measured on earth, they are not the same and...
