Who Discovered Spectroscopy?

Similar to many scientific concepts, spectroscopy developed as a result of the cumulative work of many scientists over many decades. We typically credit Sir Isaac Newton with the development of spectroscopy,

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.

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.

Is Sound Just Vibrations?
Physics

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.

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

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”?
