WebbThe motors that drive airplane propellers are, in some cases, tuned by using beats. The whirring motor produces a sound wave having the same frequency as the propeller.

WebbA wave's frequency basically just indicates how rapidly or slowly a medium vibrates as a sound wave passes through it. Scientists use Hertz (Hz) units to refer to frequency; a single vibration per second is 1 Hz. Ears are constructed to pick up on fluctuations in frequency, because a sound's pressure waves affect the eardrum. WebbIn addition to the traditional topics of mechanical vibrations and waves, coupled oscillators, and electro-magnetic radiation, students will also learn about musical instruments, red sunsets, glories, coronae, rainbows, haloes, X-ray binaries, neutron stars, black holes and big-bang cosmology.
