Resonance -- How does it occur?
I am having a little difficulty with the concept of resonance. Could someone explain how resonance occurs and how elastic oscillation relates to resonance?
So, sound is a longitudinal wave, while light is a transverse wave. The speed of sound varies going from one medium to another directly proportional to the bulk modulus and inversely proportional to the density of the new medium (i.e. from air to a steel pipe). Let's say a sound wave (consisting...
