User: How was CMB radiation first discovered? Penzias and Wilson were looking for it using a radio receiver. A radio receiver accidentally picked up its energy. Scientists saw it through a high tech telescope. A mission of the COBE satellite found it.

Weegy: It was first found accidentally by Arno Penzias and Robert Woodrow Wilson as they experimented with the Holmdel Horn Antenna.

User: How has the Doppler effect and the redshift of stars and galaxies indicated that the universe is expanding? The Doppler effect says that the higher the frequency of waves, the further an object is moving from the observer. The color red has the shortest wavelength. The Doppler effect says that the lower the frequency of waves, the faster an object is moving toward the observer. The color red has the longest wavelength. The Doppler effect says that the frequency of sound or light waves is affected by whether the emitting object is moving toward or away from the observer. The color red has the longest wavelength. The Doppler effect says that the frequency of sound or light waves determines the color of an object. The color red has the longest wavelength. Question #10TextMultipleChoice Score: The Doppler effect indicates that the frequency of energy (sound or light) waves stays the samedecreasesincreases when an object is approaching and stays the sameincreasesdecreases when an object is moving away. Question #11MultipleChoice Score: Hubble's expansion law states _____. the distance of a galaxy is proportional to its recessional speedthe universe is expandinggalaxies and stars are making a redshiftthe distance of a galaxy divided by its recessional speed determines its redshift Question #12TextMultipleChoice Score: The blue end of the visible color spectrum has shortlongno wavelengths, and the red end has noshortlong wavelengths.

Redshift means stars and galaxies are emitting a color that is shifting toward the red end of the color spectrum. This indicates the light's wavelengths are longershorter and less frequent, and the star or galaxy is stationarymoving awayapproaching
Weegy: In physics, redshift happens when light or other electromagnetic radiation from an object moving away from the observer is increased in wavelength, or shifted to the red end of the spectrum. [ In general, whether or not the radiation is within the visible spectrum, "redder" means an increase in wavelength – equivalent to a lower frequency and a lower photon energy, in accordance with, respectively, the wave and quantum theories of light. ] (More)

The Doppler effect suggests that sound waves are relative to the observer. You know if an object is coming or going from the sound it makes. Light waves follow the Doppler effect also. However, instead of sound changing, you know if an object is coming or going _____. from the brightness of the light from the color of the light from the twinkle of the light from the sound of the light
Weegy: You know if an object is coming or going from the brightness of the light. User: He originally suggested that galaxies are moving farther away. He also suggested that the distance of a galaxy is proportional to its recessional speed. He is _____.
