Is Sound Just Vibrations?

When we consider what defines sound in a physics context, it can be tempting to assume sound is basically vibrations. While partially true, sound is much more complex than simple vibrations.

What Type of Wave is Sound?
Physics

What Type of Wave is Sound?

So what type of wave is sound? Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves.

What is a Sound Wave in Physics?
Physics

What is a Sound Wave in Physics?

In physics, sound is produced in the form of a pressure wave. When an object vibrates, it creates sound energy, which causes the surrounding air molecules to vibrate, initiating a chain reaction of sound wave vibrations throughout the medium.

Texas Student Instruments Science Fair Experiment with PASCO Sensors

My name is Jonathan Shyu, and I am a student attending Colleyville Heritage High School. For my Advanced Chemistry Research and Design course, I created a biofilter, which is an air filter that uses bacteria in a preprepared compost to process harmful VOC
