SUMMARY
The discussion centers on calculating the frequency of light emitted from a receding galaxy, specifically one emitting orange light at a frequency of 5e14 Hz and receding at a speed of 3325 km/s. The correct formula to use is f' = f (1 - v/c), where v is the speed of the galaxy and c is the speed of light. The user initially miscalculated the frequency upon reaching Earth, mistakenly converting Hz to fHz, which led to confusion. The expected outcome is that the observed frequency will be slightly less than 5e14 Hz due to the Doppler effect.
