LMEC-15B Sound Velocity Apparatus Resonance Tube

Sound Velocity Apparatus Resonance Tube  The instrument uses loudspeakers to produce audible sound waves with continuously adjustable frequency, which resonates in the air column to measure the wavelength of sound waves, measure the speed of audible sound, and study the relationship between sound speed and frequency. Compared with the old equipment, the water column has the advantages of large moving range, continuously variable measuring frequency, high accuracy of measurement results, convenient use and durable structure. Experiments 1. Observe the audible standing wave in the resonance tube 2. Measure the sound velocity Main technical specifications1.
