(a) Which arrow shows the amplitude of the wave?
(1 mark)​

hmmm, where is the image?

but still let me tell you

Explanation:

amplitude of a wave is the maximum displacement of a particle from its rest position

so the arrow should be from the middle of the wave to the top of the crest or to the bottom trough,

from the middle

okay?

hope this helps, but be sure to add the image next time
