When sound waves travel through a medium, the particles of the medium move parallel to the wave motion.?

The answer is B if you get it wrong ill give you a cookie

The answer is already in the Question my friend =) A. Longitudinal wave..here's the explaination:

'Sound Waves' travel through a medium.... this is written in the question.

Sound waves is a type of Longitudinal Wave, and ONLY sound waves is Longitudinal Wave =)

For Transverse Wave, it is light wave, water wave, X-ray and so on that are shown in Electromagnetic Spectrum list.

For Longitudinal Wave : the particles of the medium move parallel to the wave motion

For Transverse Wave : the particles of the medium move PERPENDICULAR to the wave motion

A simple way to memorize the type of wave is that, for Transverse Wave, the initial is Letter T. So, it will shown like a zig zag image like you see a wave of water, zig zag or shall we say 'wave like shape' =)

As for Longitudinal Wave, you can differ it from Letter T.

Hope this simple explaination help you my friend =) I wish best luck of you in Physics

A. Longitudinal waves

The question says ''parallel'' and that can only be longitudinal. Transverse is for ''perpendicular''. Sound waves can both be parallel or longitudinal depend on the relative angle between the particles in medium and wave motion.

i think it would be transverse waves
