Infant and Toddler Activities: Young Infants, Mobile Infants, and Toddlers. Because infants change and grow so quickly, curriculum must. adjust to their developmental level. For this reason, activities are. designed as prototypes for young infants, mobile infants, and.
A standing wave in a rectangular cavity resonator. A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others.esonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones.
The resonator is designed to work best in the frequency range where the engine makes the most noise; but even if the frequency is not exactly what the resonator was tuned for, it will still produce some destructive interference.
