hi everyone...
is possible to stop light with ultrasound?
Im developing a project with and we would like to stop light with ultrasound(high frequency).
you think is better to use raspberry pi?
Cheers

I think before you decide what platform to use, you need to figure out if this is even possible
From my understanding the answer is no to stopping it, you may be able to diffract it a bit but with a PI, probably not enough to even measure
Think of standing in a room with the light on, does it get darker when you turn on a the music up loud (Short of it blowing the house fuse 
)… no, ultrasound is only marginally higher frequency than audible compared to the frequency of light and is also a completely different wave type (Movement of Air vs movement of photons through air)
Now if the ultrasound was detected by something connected to a switch and it turned off the light then sure, but I suspect this is not what you want to achieve, it is the use of Ultrasound to directly block the light and that’s what I think is the part that wont work
Just my two pence worth
Another option would be to use the ultrasound to interfere with a surface that is transparent under normal conditions but when the sound wave hits it, it vibrates / changes its properties to go opaque ? this I could see as a plausible option though I do not know the materials you would need
