Now this may sound kinda weird, but Suppose you stretch a Slinky (registrated trademark): On one side, you move your hand up and down once....one transverse wave, one wavelength... One the other side, your partner pushes forth a compression (one longitudinal wave, one wavelength What will happen when they meet? (collision between transverse and longitudnal)? Transverse waves--up and down; longitudinal, well, in the direction of wave travel, that is. Combining a forward vector from longitudinal, and the up or down vector from transverse, would I get a "diagonal" compression-stretch sequence...where the compression actually "travels" across the "up and down wave"??? Like, the compression travels right on but in the opposite direction of the transverse wave? Seems cool if it would be so.
