REFLECTION

Can you describe how a standing wave is formed? Do you know the differences between a travelling wave and a standing wave? Can you determine the wavelength of waves on strings and in pipes in terms of the length of the string or pipe? Do you know what is meant by resonance and resonant frequency? Do you know what is meant by damping? Do you know the effect of increased damping on the resonant frequency?
