Wave Properties of Sound

Postby ashwathinair » Sun Oct 20, 2019 8:19 pm

Just curious, would wave properties such as constructive and destructive interference apply to things other than light, like sound? If so, what would be an example of that?

Yes. Noise cancelling headphones are an example of this. The way they work is that they try to replicate the noise of your surrounding, but out of phase. So when the sound waves produced by the headphones interact with the sound waves from the ambient noise, wave destruction occurs and the sound is cancelled out.

Yes, I think constructive and destructive wave properties would apply to sound. Constructive waves of sound would cause the sound to be louder and destructive waves would cause the sound to be quieter. This is because in constructive waves, the amplitude of the waves increase, whereas the amplitude decreases in destructive waves,

Yes, constructive and destructive interference apply to sound (which is a longitudinal wave), you can use tuning forks to demonstrate this (it's fun to play around with them).

An example of constructive interference would be like two different speakers in the same area playing the exact same music at the exact same time. They are emitting separate waves, which are then combining to create a louder sound.
