0.25 wavelength= 0.5 pi rads
0.5 pi = 90 degrees

the peaks are curved not pointy like the one i've drawn in diagram 1....
for progressive wave the shape doesn't chnge...
for stationary after T/4 the wave becomes straight
Even I'm so confused! I believe the graph should have started from 20cm.can you explain the first graph?
Thanks so much I posted this several times and I got the answer from only you.Hey, for part b)
This is the key for this question: For minima to occur: Path difference= 0.5Lambda, 1.5 Lambda. 2.5 Lambda and so on...
If you look at the figure, you'll see that it's a right angled triangle, use paythagors theorem. You'll get S2M= 128 cm
Path diff= 128 - 100= 28 cm
Your range is from 1khz to 4 kHz
Use v= lambda x frequency
Speed = 330 m/s
Range of lambda= 8.25 cm to 33cm
Now, start trying, remember path diff= nlambda
So 28= 0.5 x Lambda, 56 not in allowed range
28= 1.5 x lambda, 18.6 allowed range
28= 2.5 x lambda , 11.2 allowed range
So 2 minima occur
Even I'm so confused! I believe the graph should have started from 20cm.
please can someone explain the following questions as soon as possible. thnx in advance and please can u draw diagrams where necessary. thnk u very much.

Can someone please explain to me Q8 part bi? Why did they take the no. Of particles of uranium? Why not barium?
Yeah me hereanyone here ?

Hey, for part b)
I just copy pasted it from one of the posts from last page
Have you done the examHow was the exam guys? I think it was all right...not THAT easy as some people think. Some parts really required thinking
Can I inbox you to ask some information on what came and firstly which variant did you giveHow was the exam guys? I think it was all right...not THAT easy as some people think. Some parts really required thinking
