其實唔係好睇得明個definition
即係longitudinal 同transverse waves,我讀更英中so用英文上堂
咩叫所謂direction of travel of wave and vibrations are perpendicilar to each other.
係咪即係如果direction of vibration係horizontal,更住direction of travel of wave就係vertical motion ?好abstract 呀！仲有我有d例題想俾大家睇，甘可以解埋俾我聽!
有哪裡可以上載相呀？

✔ 最佳答案

Your understanding of transverse wave is correct.

Along "south-north" direction means a line running from south to north. Likewise, along "east-west" direction means a line running from east to west.

You could look at the animation via the following link:

Here the wave is travelling from left to right, but the marker (the red dot) is vibrating up and down only.
