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™ 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.
Fisher Science Education Three-Wire Pattern Sonometer
Hollow wooden sounding box with scales between fixed bridges.
3B Scientific™ Electric Doorbell
Demonstrates electro-magnetic operation and verifies that sound waves do not propagate in fine vacuum.
3B Scientific™ Kundts Tube
Demonstrate standing sound waves using this glass tube and calculate wavelengths of sound using a method devised by Kundt.
Fisher Science Education Simple Resonance Tube Set
Demonstrates the principles of resonance without requiring a water column or other apparatus.
3B Scientific™ Resonance Ring
Demonstrates vibration knots in determination of different frequencies.
Fisher Science Education Wave Demonstration Apparatus
Demonstrates both longitudinal and transverse wave motions.
EISCO Doppler Effect Demonstration Apparatus
Load batteries, swing the device in a full circular motion experience the doppler effect first hand. The EISCO Doppler Effect Demonstration Apparatus is the perfect demonstration of the Doppler effect in a classroom.
GSC Intenational Graduated Resonance Tube
Choose GSC tubes for demonstrating resonance in the classroom.
GSC International Resonance Apparatus
Ideal for demonstration of standing waves. GSC International Resonace Apparatus can be used to observe resonance phenomena, speed of sound in air by exploiting standing waves, resonance effects in longitudinal waves, and resonance points for certain frequency and their relation with standing wavelength.
