I think sound has a much higher frequency of waves and that allows the sound waves to survive bouncing off of objects where light just dies on impact.

At least that’s what my gut says.

Correct. Don’t know what i’m being downvoted for lol.

Sound waves have a lower frequency than light waves, and this means that they can travel through solid objects and around corners. This is why you can hear sounds that are coming from behind walls or other objects. On the other hand, light waves have a much higher frequency and are not able to penetrate solid objects as easily, which is why light can be blocked by walls, curtains, and other objects. So the lower frequency of sound waves allows them to persist even after they've been reflected by solid objects.

This makes perfect sense and I had it totally backwards. I think my completely backwards answer is rubbing off on you.

At the very least I now know the truth. Thanks!

Audible sound runs from about 10 Hz to about 25,000 hz.

Visible light runs from 4 x 10 E 14 hz to 8 x 10 E 14 hz. ( 10 E 14 hz is 100 Terahertz )
