Does light energy(waves) affect sound waves...? i read in one post that light affects sound indirectly.If yes how do we relate and calculate that..?

Discussion Overview
The discussion revolves around the relationship between light and sound waves, specifically whether light energy can affect sound waves and how these interactions might be quantified or experimentally tested. The scope includes theoretical considerations, experimental proposals, and conceptual clarifications.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- Some participants propose that light waves do not affect sound waves directly, while others suggest that sound waves can influence light, particularly in scenarios involving loud sounds or shockwaves.
- One participant emphasizes the need for experimental verification of claims regarding the interaction between light and sound, suggesting specific methods for testing.
- Another participant discusses the concept of light affecting sound indirectly through changes in the medium's properties, such as heating a non-transparent medium.
- A participant references an experiment involving a Tesla coil to illustrate a potential relationship between light and sound, noting that sound is produced by vibrations in the air.
- There is a request for clarification on a previous post that mentioned light affecting sound indirectly, indicating a desire for more specific references or examples.
Areas of Agreement / Disagreement
Participants do not reach a consensus on whether light affects sound. Multiple competing views are presented, with some asserting no direct effect and others suggesting indirect interactions through medium properties.
Contextual Notes
Participants express uncertainty regarding the definitions and implications of light affecting sound, and there are unresolved questions about the specific phenomena being referenced in the discussion.

Hi kalkish! Welcome here to Physics Forums.
At first sight I'd say, No, lightwaves do not affect sound waves. But just be sure, can you please explain in more detail or post the reference you used? There may be more science (physics) underlying this.
Cheers, Bobbywhy

I'd say no, but the opposite is certainly true - sound waves will affect light, especially if the sound is extremely loud, as in the shockwave from an explotion. The increased density of air at the wavefront will change the index of refraction, causing optical distortion.

The only way to be sure is to devise an experiment, I didn't see any of the other posters citing a reference to their answers so would consider them more of a personal opinion at this point. But that is just me, perhaps they will cite reference(s) after reading my post (idk).
I would recommend using a combination of these resources:
1. tool(s) to measure sound intensity
2. various levels of sound/notes to test
3. various light intensities to test

Hello,
What is the meaning of light energy affect the sound ?
In this experiment "Tesla Coil Control With XBOX Kinect" we could say that there is a relationship between light and sound.
Originally, a Tesla coil does not generate notes. Sound is a wave that reaches the ears by vibrating air. By extension, anything that can vibrating the air is likely to create the sound. For example, a loudspeaker is a transducer that changes an electrical vibration intensity by a magnet fixed to a membrane.
Electrical arcs generated by Tesla coil vibrating the air, like the diaphragm of a speaker.

Which post? Can you give us a link? Then we can comment on the specific phenomenon that the post is talking about, instead of trying to guess what it is.

If the medium through which the sound is traveling is not transparent then light would heat the medium, changing its acoustic properties.
