some misunderstanding i've about waves

[kevin86]

are questions involving a rope vibrating, standing waves, and all transverse waves? Can someone categorize which other wave is longitude other than sound and which is transverse. Is light transverse or longitudinal, and why, or how can you tell.

I would appreciated someone clear it up for me.

In each case, ask yourself...

In which directions do the oscillations [of the thing that is waving] occur?
How does that compare with the direction of propagation of the disturbance?

(i.e. What are the definitions of "longitudinal" and "transverse"?)
