1. Hold a tuning fork in front of the microphone. Draw the trace on the CRO.

Would anyone happen to know how the trace would look like? I tried searching for it but couldn't find anything. An attachment diagram is greatly appreciated. Thank you.

2. See attachment. I need help with the questions I haven't answered because I'm a bit confused with the model of the longitudinal wave. Any outside resources or websites which will assist me will be greatly appreciated.

Thank you.

Question 1
Sound is a longtitudinal wave. If you use a tuning fork, i expect the sound to be pure (no random vibration's like from your vocal cords when you speak). I think CRO's convert the longtitudinal wave to a transverse wave. So for a tuning fork, it would look like a sine curve but the amplitude would slowly decrease as the fork stops vibrating

Attatchment
Question 1
Point 3 - decelerating
point 6 - accelerating
Point 11- accelerating

Im not sure about this q. but it seems logical that for a stationary object to get to maximum speed it has to accelerate?

Question 2
No idea

Question 3
At the centre of compression in the longtitudinal waves draw the arrows of the points surrounding it into centre of the compression.
DO the opposite for rarefaction
Not really sure, check your textbook

Question 4
a) Compression
b) Rarefaction

My prelim knowledge is kinda rusty. Hope it helps however

Thanks namburger. At least one person actually replied to my thread in a while .
