>"Waves In the end, it all comes down to something pretty simple. All types of signals or functions, no matter how complicated, are really superpositions of sine waves. That is pure waves that have a well-defined constant wavelength and amplitude. A superposition simply means that all the waves interact and the sum of all the waves (called interference) is then the superposition that makes up the more complicated signal." I agree! But, here's a related question... All waves require some medium of oscillation/vibration. In Classical Physics, you might think of this as a rope which has tension which is tied between two poles, or an instrument string, tied between two points on the instrument, and also under tension... Well... here's my question then... Let's suppose that a) That the rope or string that connect the two points under tension -- is so strong that it cannot break under any circumstances And that b) More and more (increasing) tension is applied to the rope or string between the two points -- until the tension becomes INFINITE... or close to it... Now, here's the question... When the medium of the transmission of a wave (or wave packet, i.e., superposition of waves) reaches (or approaches) INFINITE tension -- then what happens? That's question #1. Question #2... How does approaching INFINITE tension in a medium -- affect the SPEED of waves using that medium to travel in? Do they move faster, slower, or at the same speed they always moved at? And WHY? ?
