<h2>Answer: Light waves have a redshift due to the Doppler effect
</h2>
The astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed the spectral lines were displaced towards the red (red shift), whereas the nearby galaxies showed a spectrum displaced to the blue.
From there, Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum. <u>The same happens with the stars and this phenomenom is known as the Doppler effect.
</u>
This phenomenon refers to the change in a wave perceived frequency (or wavelength=color) when the emitter of the waves, and the receiver (or observer in the case of light) move relative to each other. For example, as a star moves away from the Earth, its espectrum turns towards the red.
You didn't post any choices. A microwave Photon carries more energy than a radio wave photon. An infrared Photon carries more energy than a microwave photon. A visible light Photon carries more energy than an infrared photon. An UltraViolet Photon carries more energy than a visible light photon. An x-ray Photon carries more energy than an UltraViolet photon. A gamma ray Photon carries more energy than an x-ray photon.
Answer:
liquids and gases
Explanation:
Liquids and gases are considered to be fluids because they yield to shearing forces, whereas solids resist them.
Answer:
An atom of Cu-63 has 34 neutrons and an atom of Cu-65 has 36 neutrons. 27- The total number of electrons in an atom of Cu-65 is 29 because copper has atomic number of 29, which simply means that an atom of copper has 29 protons and 29 electrons.
Explanation:
The therapeutic technique Lucinda would start is behavioral self-monitoring.
<u>Explanation:</u>
Behavioral self-monitoring, introduced by Mark Snyder in the 1970s, is an ability of an individual to regulate the behavior to accommodate in various social situations.
Here, Lucinda frequently gets upset and yells at her husband, co-workers, and friends. She wants to keep a record of where, when, or with whom she might lose her temper in order to evaluate her behavior.
The individuals with high levels of self-monitoring possess greater skill at bridging social situations and in relationships they seem to be more flexible and adaptable.
