Based on the hypothesis (Big Bang theory) that the universe is expanding, an analysis of light wave would indicate: A. a decrease in frequency and a red shift.
<h3>What is a redshift?</h3>
A redshift can be defined as a displacement (shift) of the spectral lines of an astronomical (celestial) object toward longer wavelengths and a corresponding decrease in frequency, as a result of the Doppler effect.
Basically, a redshift occur when observing an astronomical (celestial) object from planet Earth because it's receding (moving away) from planet Earth.
In conclusion, we can infer and logically deduce that an analysis of light wave would indicate a decrease in frequency and a red shift based on the hypothesis (Big Bang theory) that the universe is expanding.
