Joule's classic experiment. A fascinating study of mechanical resonance between two types of simple harmonic motion. An investigation of vibrations in a tuning fork subject to damping, using a storage oscilloscope. Temperature dependence may be studied. The study of the motion of solids in viscous fluids in both laminar and turbulent regimes.
Emphasis is placed on considerations involving the changing of scales of the physical quantities.
An acoustic analogue of seismic reflection measurements similar to those used in exploration geophysics. Measures the velocity of sound in air. Quantitative comparisons with theory can be made. Wave effects observed using microwaves with a wavelength of 3 cm. A fairly qualitative experiment.
