About This Product
Starting at a low driving frequency, students raise it gradually and record the amplitude at each setting, noting the frequency at which the amplitude is greatest. The results explain resonance, the difference between natural and driving frequency, and how energy passes into a vibrating system. Enquiries from Central African Republic, Papua New Guinea, Egypt, Georgia and Benin for the Forced oscillation apparatus receive an export quotation.
Frequently Asked Questions
What is resonance on the Forced Oscillation Apparatus?
It is the driving frequency at which the amplitude of the oscillator becomes maximum.
