General Aim | Speed of Sound Virtual Lab Using Open Columns
Measuring speed of sound in air at room temperature in a speed of sound lab.
Method | Speed of Sound Virtual Lab Using Open Columns
Open Air Column.
Learning Objectives (ILOs)
By the end of sound waves experiment, students will learn to:
Explain the resonance phenomena in an open air column, also known as resonance of air columns by using Speed of Sound Virtual Lab - Using Open Columns.
Set up a speed of sound using open air columns experiment and determine the speed of sound in air.
Theoretical Background / Context
- When a sound source (wave generator) is held at one end of the open air column (tube), standing waves are generated inside the columns.
- Resonance (loudest sound) occurs, when the frequency of the air column is the same as the frequency of the source.
Principle Work of Measuring the Speed of Sound Experiment
In the speed of sound virtual lab using open columns:
By determining the resonance’ position and correlating the relation between the wavelength of the fundamental tone formed and the frequency of the source, the speed of sound in air at room temperature can be estimated.
“With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.”
'' Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab, solution: PraxiLabs.''
" PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs."
"Great user experience and impressive interaction, I am very pleased to have tried the simulations and will continue to do so."
