Resonance kit

A kit for precisely determining the wavelength of sound waves in air. It comprises the ‘compact’ resonance tube P1350-2K (a sturdy acrylic tube with a transparent scale, L = 500 mm, D = 50 mm), the matching piston P1350-2S, and the small holder P1351-2H for marking maxima and minima on level surfaces. The set also includes the MBC loudspeaker MB240-1LS (8 Ω / 1 W, two 4 mm jacks) with a tube for connecting to the resonance tube.
