# 2016 Official AQA New Spec AS Level Physics Paper 1 - 24th of May 2016 watch

1. (Original post by JTawn)
I reckon it said the air left at a higher speed and you assumed it was the same mass?
That is exactly what I did.

p = mv

higher v and constant m = higher p

Lol I definitely got this wrong but wavelength was 12cm and then you can use v=f x wavelength to find f. I reckon some marks will be for showing you measured the diagram and then the rest for the working
but we dont know the speed, do we?

The deflector plates caused a change in direction
I wrote : I wrote momentum is a vector and therefore has direction. One side must be considered negative. Either change in momentum = mass x final velocity - - mass x initial velocity OR = mass x - final velocity - mass x initial velocity
Both scenarios would cause a change in momentum even if the velocity is the same.

Okay sorry no need to get rude...
I apologise, looking back, it came across rude. I didnt mean that to be the case

Yeah I said the same, nice
6. For microwave, if you said wavelength was 8cm instead of 12, how many marks will you loose ?

3x108 because it's EM radiation. I totally had a mind blank also don't worry
8. Has anyone made an unofficial mark scheme for this paper ?

If you use the right equation after you'll probably get some marks maybe 2/5??

I think she meant c = f*wavelength

(c and v are close on the keyboard)
11. (Original post by wolvan)

Not if you think of it as V= fx, thinking of it as C=fx where c is the speed of light is what ya want

but that's only in vacuum though?

Don't worry about it. Realistically no one knows the right answer anyone because it's likely we've forgotten the questions because exams are stressful. What we need is an unoffical markscheme!!

If they don't give us a way of working it out, I think we assume it's the same, otherwise I have no idea what it could be

at least 1 for getting it wrong and 1 for wrong final answer

Indeed we do

Speed of em waves are 3x10^8

Haha I do chemistry too- mixing up my letters in the equations!!
19. (Original post by JTawn)

Atleast we have scored 1/70 then

was looking at the physics and math tutor web, but it seems they only upload math ones
