Eisco Labs Resonance Apparatus provides students a hands-on method for exploring the relationship between sound frequency, wavelength, and velocity. Standing approximately 43" tall, the apparatus features a clear, graduated acrylic tube (~40.75" x 1" diameter) and a sturdy metal base (10" x 11") with clampable edges. The adjustable water level within the tube demonstrates resonance, allowing accurate calculations of sound speed. Included are two ring clamps (1.25" and 3" diameters), a metal vessel, and rubber tubing (~39.5"). Requires tuning forks (sold separately; recommended: EIS-6783). Ideal for physics education, sound experiments, and STEM demonstrations, offering students engaging exploration of wave properties.
