Responses
when the object is stationary
when the object is stationary
when the object is in the same frame of reference as the scientist
when the object is in the same frame of reference as the scientist
when the object is moving away from the scientist
when the object is moving away from the scientist
when the object is moving toward the scientist
when the object is moving toward the scientist
The scientist will observe redshift in the spectrum of a distant space object when the object is moving away from the scientist.
A scientist will observe redshift in the spectrum of a distant space object when the object is moving away from the scientist.
A scientist will observe redshift in the spectrum of a distant space object when the object is moving away from the scientist.
Redshift is a phenomenon that occurs when the wavelengths of light emitted by an object are stretched or lengthened as the object moves away from an observer. This results in a shift towards the red end of the electromagnetic spectrum.
To observe redshift, scientists typically analyze the light emitted by distant space objects, such as galaxies or stars, using a spectrograph. By examining the spectrum of light, scientists can detect any shift towards longer wavelengths, indicating redshift.
Therefore, when a distant space object is moving away from the scientist, the light it emits will undergo redshift, allowing the scientist to observe this phenomenon.
