A distant galaxy emits light that has a wavelength of 702.8 nm. On earth, the wavelength of this light is measured to be 704.2 nm. (a) Decide whether this galaxy is approaching or receding from the earth. (b) Find the speed of the galaxy relative to the earth. (Give your answer to 4 significant digits. Use 2.998 x 108 m/s as the speed of light.) (a) The galaxy is receding from the earth. (b) Number _______ Units m/s
4.4 A star is receding from the earth at a speed of 5 x 103 c. What is the wavelength shift for the sodium D2 line (589 nm)?
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...
The galaxy Palioxis is receding from the Milky Way at a speed of 0.35c. Another galaxy, Euthenia, is receding from the Milky Way in exactly the opposite direction, but at a speed of 0.45c. (a) For an observer in Palioxis, how fast is the Milky Way receding from them? Explain from them? Explain (b) For an observer in Palioxis, how fast is Euthenia receding f Imagine two muons, symbol μ-, moving towards each other with equal and opposite speeds. If...
Astronomers determine that a nearby galaxy is moving toward our galaxy at a speed of 723.0 km/s with respect to the Earth. If Earth receives a wavelength λ = 679.1 nm from a particular star in this nearby galaxy, what was the wavelength emitted by the star? (Give your answer to at least three significant figures.)
Chapter 24, Problem 35 Interactive Solution 24.35 to see one model for solving this problem. A distant galaxy emits light that has a wavelength of 525.4 nm. On earth, the wavelength of this light is m galaxy is approaching or receding from the earth. (b) Find the speed of the galaxy relative to the earth. (Give your answer to 4 significant digits. Use 2.998 x 108 m/s as the speed of light.) (a) The galaxy isfrom the earth. (b) Number...
1. Doppler shifts have been used to determine the rate of expansion of the universe. a) Given that a distant star is receding at a speed approximately 8% of the speed of light, determine the shift in the observed wavelength for a particular spectral line of 3 ps* that normally has a wavelength of 326 nm b) The FWHM of the spectral line mentioned in the previous problem is 53.8 pm. What is the surface temperature of the star? 1....
1.) At what distance would a satellite orbiting the Earth be geosynchronous (orbiting the Earth once every 24 hours)? It would be geosynchronous at _________ × 104 m from the center of the Earth or __________× 104 m from the Earth's surface. 2.) Hydrogen also produces spectral lines at radio wavelengths, notably at 21.1 cm. If a galaxy is moving away from us at 9% of the speed of light, at what wavelength will we detect this line? Convert this...
