SUMMARY

The discussion centers on the feasibility of transforming radiowaves into visible light through the principles of Doppler shifting. It confirms that as a rocket approaches a radio transmitter emitting radiowaves at 100 femtometers, the waves can indeed be shifted to higher frequencies, potentially reaching the visible spectrum. The conversation also touches on the concept of increasing energy of the waves during this process and references phenomena like N-Wave and Čerenkov radiation, highlighting the complexities involved in such transformations.

PREREQUISITES
  • Understanding of Doppler Effect and Doppler Shifting
  • Familiarity with electromagnetic spectrum and wavelength measurements
  • Knowledge of Čerenkov radiation and its implications
  • Basic principles of wave energy and frequency
NEXT STEPS
  • Research the principles of Doppler Effect in various contexts
  • Explore the electromagnetic spectrum and its applications in communication
  • Study Čerenkov radiation and its significance in particle physics
  • Investigate the concept of wave energy and frequency transformation
USEFUL FOR

Physicists, aerospace engineers, and anyone interested in the interaction of waves and energy transformations in advanced communication technologies.

If a rocket is flying towards a radio transmitter that emits radiowaves (100 fm for instance) fast enough. does these radio waves get stacked up and become visible light.

extrapolated question. can we (by changing the relative velocities between transmiter and receiver) shift from any wavelength to any wavelength?

Yes. Standard Doppler Shifting.
 
And while that is going on you measure increasing energy of the waves as well...
 
Hmmm... it sounds like the N-Wave in trans-sonic flight! Of course, there is no trans-c flight, and I guess Čerenkov Rad is that "boom", short of an FTL miracle/catastrophe.
