They usually allow either! But I'd always check the formula sheet just in case.

Yh thnx

pls someone tell me the definition of redshift and blueshift?

Just did a question on it so this is from the mark scheme for red shift:

increase in wavelength (of em radiation) due to relative recessive velocity
between observer and source 

Can someone please explain proper length vs normal length to me? I thought I understood which is which but I'm still getting it wrong in questions :'( Why is 4aii) in June 2011 not proper length?

Has anyone by any chance made a list of all the 6 marker topics on the main paper over the past few years? :smile:

June 10 - nuclear reactors and fission
June 11 - how a gas exerts pressure
June 12 - nuclear radii
June 13 - verifying types of radiation emitted by a source

June 14 - nuclear waste

June 15 - maybe something about gases?

Does anyone have a full derivation of the kinetic theory equation

oh hell no gas please :frown:

I am hoping for nuclear reactor or stuff about nuclear energy, that will be nice

Staying up late but not because of that, have to memorise all the bulls*** nuclear safety stuff ffs

Sorry mate but that's what i think, only one gases question ever. They've pretty much exhausted the nuclear topic in terms of 6 markers

I'll be joining you, the whole of my unit 5 wasn't taught properly -.-

Waayyy too much memorizing in nuclear/gases and astro... most of it won't even come up

I wouldn't really say I was "taught" astro. Moreso than some dude came in and had this delusional idea he taught us everything on the specification and expected us to past papers.

Self-study wooop!

I really hope gases doesnt come up or any experiment ones altho i think electon scattering is a good one and only a comparison of alpha and electron scattering has come up before so hopefully!

What sort of gases question are you thinking then?

maybe kinetic theory of gases equation derivation?

hoping for comparison of 2 methods of finding nuclear radius!
