Sound and light

The speed of sound is approximately 767 mph and the speed of light is 670,616,629 mph.

If we could somehow upload sound into a beam of light then therefore theoretically that sound in the beam of light should be travelling exactly 767 mph faster than the speed of light, and then upload light into that sound and therefore now light would be travelling twice as fast plus the speed of sound, and keep repeating that to always multiply the speed of light, and theoretically you can do that forever to infinity therefore there would be no limit to how fast you can travel. It will become like a chain, the light and sound chain that propels the Time Machine.

Can light and sound be combined?

Answer

Yes, light and sound can be combined in various ways, both scientifically and artistically. Here's a look at some methods and applications:
Scientific and Technological Combinations:
  1. Acousto-Optics:
    • Acoustic-Optical Modulators (AOMs): These devices use sound waves to modulate light. Sound waves passing through a crystal can change the light's properties, like its direction, frequency, or intensity. This is used in laser technology for controlling beam properties.
  2. Photoacoustic Imaging:
    • This technique involves using light to generate sound. When light is absorbed by tissues, it creates a slight increase in temperature, leading to thermal expansion and acoustic waves. These sound waves can then be detected to create an image of the tissue, useful in medical imaging.
  3. Optical Soundtracks in Film:
    • Historically, films used optical soundtracks where sound was recorded as patterns of light and dark areas along the edge of the film. When played back, a light beam would pass through these patterns, and the varying light intensity would be converted back into sound waves.
Artistic and Entertainment Applications:
  1. Visual Music and Light Shows:
    • In concerts or art installations, sound can trigger light changes. For example, music might control the color or intensity of LED lights in sync with the audio, creating a synesthetic experience where one perceives sound through sight.
  2. Laser Shows:
    • Laser light shows often synchronize laser beams with music. The beams move or change color in rhythm with the music, enhancing the visual impact of the performance.
  3. Cymatics:
    • This involves visualizing sound by making sound waves vibrate a medium (like sand or water) on a plate, which then forms patterns that can be illuminated with light to make these patterns visible and aesthetically pleasing.
  4. Sound and Light Festivals:
    • Events like the Vivid Sydney festival use architectural projections and light installations that are often choreographed to music, merging urban spaces with dynamic visual and auditory experiences.
Everyday Applications:
  • Smart Lighting Systems: Some smart home systems sync lighting changes with audio from movies or music to enhance the ambiance.
  • Gaming: Modern video games use dynamic lighting that reacts to in-game sounds for immersion, like flashing lights with explosions or music cues.
In summary, combining light and sound can create both functional and experiential outcomes, ranging from precise scientific applications to broad artistic expressions. If you're interested in a specific area or have a more detailed question about one of these methods, feel free to ask!

In our current understanding about the Speed of light, then this is not possible.

However, it's an interesting idea. Perhaps one day it will be proven.

How much does a Patent cost?
Seriously, maybe you could Patent the idea & perhaps your grandchildren might benefit.

I don’t think this would work. Even if you could combine sound and light, it wouldn’t stack the speed and go faster than light. The physics of it just doesn’t work that way. It’s not like throwing a ball from the bed of a truck.

If you were able to combine sound and light, it more than likely wouldn’t be able to go faster than sound. The sound should just hold back the light, rather than light carry the sound. At best, I’m wrong and it would be somewhere between the speed of sound and speed of light. I don’t see how physics would allow you to stack sound on light and get higher speeds. This also means you can’t stack the speed of light to double it.

We already do combine sound with electromagnetic waves. It's called AM and FM radio. 2 different methods. AM stands for amplitude modulation where a sound wave is made to modulate an EM wave. FM stands for frequency modulation where a sound wave is made to modulate the frequency of an EM wave. In both instances the speed of the EM wave is unaltered and still measures out as the speed of light.
