Description
The concept of sound waves is central to our everyday experience and part of upper-secondary school physics. Acoustic levitation represents an application of standing-wave phenomena, which has seen a surge in popularity due to the introduction of cost-effective ultrasonic speakers. However, acoustic levitation by affordable speakers remains absent from most upper-secondary physics education. Therefore, we developed LeviLab; a low-cost, user-friendly, and easily reproducible acoustic levitation experiment to measure the wavelength and speed of sound. This study proposes using LeviLab to integrate acoustic levitation into the classroom setting to measure absolute zero.
