how are we supposed to draw the stationary wave?? the question with 3 dang marks! and the graph questions? I did a straight downward line (diagonal/slope) for the acceleration.... and the other graph i did nothin

for the stationary wave you had to draw the same wave but with less amplitude!

Ouch...i drew a horizental line through the origin......But wait...why less amplitude ?

 

[pakiboy]

bcz the crest and troughs are fixed in a stationary wave and the particles were already at their max amplitude!

what does the graph of question 2 look like??

That's the correct answer. Straight line through origin
