3B Scientific™ Kundts Tube
Demonstrate standing sound waves using this glass tube and calculate wavelengths of sound using a method devised by Kundt.
EISCO Melde's Apparatus
Designed to show the effects of vibrations in a stretched cord, and investigate the relationship between frequency, tension and density.
3B Scientific™ Electric Doorbell
Demonstrates electro-magnetic operation and verifies that sound waves do not propagate in fine vacuum.
3B Scientific™ Graduated Monochord
Investigate the pitch of vibrating strings as a function of their tension, length, and thickness.
3B Scientific™ Helmholtz Resonator
Hollow glass bulb with a narrow tube leading out for demonstrating acoustic resonance.
3B Scientific™ Resonance Ring
Demonstrates vibration knots in determination of different frequencies.
GSC Intenational Graduated Resonance Tube
Choose GSC tubes for demonstrating resonance in the classroom.
Sper Scientific Analog Sound Level Meter
Sound level meter ideal for use in environmental noise experiments
GSC Resonance Apparatus
A simple apparatus that measures the velocity of sound in the air. The GSC Resonance Apparatus measures the velocity of sound in the air. Partially fill the resonance tube with water and then sound a tuning fork of known frequency at the tubes open upper end of the Resonance Tube.
