P1 physics edexcel did you guys find it awful?!

In my view, the examination was by far more challenging than any past papers: the application of physics in models and diagrams constituted a much bigger proportion of the exam than in previous years, and the last six-marker tested knowledge which many candidates probably overlooked.

The questions not only required background knowledge, but the ability to discern how to use that background knowledge - so many of my friends, for example, stated that the star was moving further away from the Earth because they knew about redshift as background knowledge, but didn't realise that the difference in wavelength meant that this was not an example of redshift, but of blueshift, because the wavelength was shortened fractionally. And of course, that last six-marker not only required knowledge on seismic waves, but also knowledge on the importance of their properties - as aforementioned, knowledge which many candidates probably overlooked. It wasn't just about knowing facts; it was about applying them.

I'd be surprised if the grade boundaries didn't fall this year. The exam was challenging, definitely. On-the-whole, judging by the answers of my friends, it looks like I've done far better than I thought I'd done coming out of that exam room. Nonetheless, with so much reliant on such small snippets of knowledge, I'm not sure what grade that will translate as.

I got that

What about the three mark question stating the sun's wavelength and then saying another star's? Was it because of red-shift and it's expanding so it's closer to the red of the spectrum or something?

What did you guys put for the wave frequency when we were given wave speed and wavelength?
I got something like 3.45x10^14

Nevermind it was blue shift, I was going to put that aswell :/

For the very first question what did everyone put as an advantage and disadvantage of the petrol fuelled generator?

I put 100p when the answer for the cost was 1000p how many marks would i get if it is 1/10 of the original answer (3 marks) 1 or 2 marks?

I said an advantage was that you can use the petrol engine all the time (as long as you have petrol haha) whereas a wind turbine needs wind to be powered that is not always available

What did people put for the question, how many years until the sun becomes a white dwarf?

Yeah I said that too, that there weren't any specific weather requirements to use the petrol generator For a disadvantage I said that the generator would need to be powered by fossil fuels which are non renewable whereas the wind generator uses it from a renewable source?

The question on the 1850nm wave difference.

I put its because microwaves are absorbed, was that right?
