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...

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 = 2.20 × 106 m/s. Relative to the center, the tangential speed is vT = 0.550 × 106 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...

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...

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?

When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
