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?
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?
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
Using the PASCO Smart Cart to Teach the Right-Hand Rule
We high school physics teachers tend to associate the right hand rules with electromagnetism. As a student, my first encounter with a right hand rule was when I was introduced to the magnetic field produced by the electric current in a long, straight wire
Outdoor Explorations in Photosynthesis and Respiration
PASCO’s Wireless carbon dioxide Sensor provides a powerful opportunity for students to explore the effects of photosynthesis and respiration in their local environment. This blog will describe how students can use a “Pretzel Barrel...
The View from a Small Town Physics Classroom
Using the new PASCO equipment we can do labs 100 times a class and the discussion becomes more in-depth. Why did they choose the data set they are using? What makes that data “better”?
Seven Things To Do With Wireless CO2
Measuring Carbon Dioxide has many applications in the classroom and with the latest advances in technology is easier and more affordable than ever before. Here’s a quick look at some of the cool things you can do...
