do you know for the stationary wave and identifying the points which was the max and min speed and phase to each other was it actually out of 6 marks for that small thing?

Omg, that makes so much sense. I put the same value again, but I spoke about the wavelength decreasing in proportion to the frequency increasing was it 2 marks?
AHAHAHA after all that earlier i'm pretty sure i did write this :/

Not sure if anyone has posted about this but you know the question where we had to draw the movement of particle X from t=0 to t=0.4, did anyone draw a line that looked like the cosine graph? No one else in my class did.
Yeah, mine was cosine. With a period of 0.2s.

There was a question where it asked for two phase differences, I think it was on the Young's double slit.
I think I put 180° and 360°, anyone??

at frist i put pi and 2pi
which is equivalent to your answer
but then i changed it to 3pi and 4pi

Yes I'm aware they get extra time for minor disabilities. I'm just saying they don't always necessarily need it...
Who are you to say if they need it or not? There's no point getting bitter because they had more time than you, for all you know there were people with extra time who did much worse than you. Focus on your next exam / something productive / future studies / ANYTHING instead of getting jealous just move on, you probably did better than you think.

ok thanks
More like 1, maybe 0, since the question was out of 2. I did the same, but I'm trying to be realistic I reckon 1/2 would be most likely

As did I, I think I put 180 for the dark fringe and 360 for the bright one

Where did I suggest I was getting jealous? I said I didn't blame my friend for taking it. I just don't think the distribution of time is fair, that's a perfectly reasonable opinion to have. Stop being so presumptuous.
