SUMMARY
The discussion centers on the behavior of light as one moves away from a light source. It is established that the wavelength of light remains constant, while the frequency appears to decrease due to the Doppler effect. Specifically, light sources moving away from an observer exhibit a 'red shift', indicating longer wavelengths, while those moving towards the observer show a 'blue shift' with shorter wavelengths. The speed of light remains constant at approximately 299,792 kilometers per second, regardless of the observer's motion.
