Do they tell us if we get marks for significant figures?
in the mark scheme it says not to penalise significant figures. There is supposed to be only 2 marks per paper allocated to significant figures and it should be stated in such a question "quote your answer to an appropriate significant figures.

I don't remember seeing that here so will those be for the second paper?
I got that at first but then realised it was 5 marks so that seemed to generic. I then found the waverlength to be 0.24 as is was the second harmonic then subbed that in getting 1.25 x10 to the power of 9.
The second harmonic is 2 half wavelengths which is the length anyway though
I got 2.4 for part 1 I got somet like 0.064 for part 2 And for part 3 I got somet like 1.2???
I'm not too good at electricity tho. Did you get any similar?
I got 2.3 for the first and something like that for part 2 but part 3 was a blur! If anyone remembers the numbers I would like to try to work it out again..
Yh but they need to find better applications to use. Its supposed to be theoretical, we're studying physics not applied physics!
Understand your point but at the end of the day, it's not much use just knowing about the theory. The implementation of theory to real life is more important
