Almost All About Waves

This text considers waves the great unifying concept of physics. With minimal mathematics, it emphasizes the behavior common to specific phenomena—earthquake waves studied by seismologists; waves and ripples on oceans, lakes, and ponds; waves of sound that travel through the air; mechanical waves in stretched strings and in quartz crystals that can be used to control the frequency of radio transmitters; electromagnetic waves that constitute light, and that are radiated by radio transmitters...
