Answer to Question #206897 in Classical Mechanics for Rae

Question

Which statement is true?

A: In case of longitudinal waves the direction of oscillation and propagation are perpendicular to each other.

B: Mechanical waves can only be transverse.

C: Mechanical waves propagate as transverse waves only in solid materials (and partially on liquid surfaces).

D: Waves always carry material.

Waves are propagating on the surface of water towards the shore with a velocity of 1.5 m/s. The distance between two neighboring crests is six meters. There is a piece of wood somewhere further in the water that turns up and disappears periodically as the water waves when you are looking at it from the shore. Calculate the time interval between two turn-ups.

If you could explain in detail itd be great!
