Wireless Speed Of Sound Pack

This Wireless Speed of Sound Pack offers a dynamic and hands-on way to explore fundamental principles of physics, especially those related to acoustics and material properties. This highly adaptable kit enables students to investigate how the speed of sound varies between gases and solids, shedding light on the relationship between wave propagation, material density, and elasticity. The robust and compact sensor design, paired with a high-sensitivity microphone pair, allows for accurate measurements both inside and outside the classroom. Whether examining how sound waves transition into shock waves in air or analysing elastic deformation in solids, this pack delivers insightful, real-time data. Its ease of setup and connection through Bluetooth or USB streamlines the experimentation process, encouraging students to focus more on experimental design and scientific reasoning. The included EasySense software provides both automatic and manual data analysis, reinforcing data literacy and interpretation skills. From first principles to advanced evaluations, this kit transforms complex concepts into tangible, visual experiences that elevate student engagement in the physical sciences.
