I'm sure you could.. because i'm leaving out all of electricity, heat and magnetism.. except for the heat experiments..

Question 5 - Short Q's
Question 6 - Mechanics
Question 7 - Light/wave/sound/heat*
Question 8 - Electricity/magnetism
Question 9 - Nuclear physics/electron/photoelectricity
Question 10 - Particle physics
Question 11 - Changes each year
Question 12 - changes all the time

*Questions 7,8 and 9 change around each year but they're usually the same topics.

I'll be covered for most of Q5, and of the other 7 I'll surely be able to do 4. You must take into account the the choice in q12 as well. I'm sure I'll be fine. Going back through the years it seems I'm plenty covered. Thanks.

Lads ye shouldn't really leave chapters out, all the science subjects (particularly Biology) are throwing bits in from different chapters in each question in recent years.

I agree..it can be a risky business leaving out certain topics. Even if the sections you have prepared appear on the paper the questions might be very tricky.. so essentially you are cutting out choice.

Cardor

Its a bit late advising people not to leave out chapters considering the exam is tomorrow.. Tonight requires smart studying and a smart student would study what he/she believes is going to come up.. spend the day studying a chapter in depth which you believe might come up.. trying to flick through every chapter is illogical!

Hi just wondering does any one know if its ok for the monochromatic light experiment to just know the method using a laser?

Yeah you can, I've always done it that way and it was marked right in my mocks. Also it's tipped to come up this year so know it people!

yes that method is suitable

Just a small tip for ye! When doing calculations and you have got a number look at the number and think is that possible. For example if you have to get the frequency of a gamma ray and it is 2*10^-15 you should know that a gamma ray will never have a value like that. Hope that makes sense!

So screwed for this.....Would it be worth attempting the paper (got 38% in the mocks and dont see myself improving too much on this) or just asking for the ordinary level? They should have spares for the ordinary level, right?

just to let you know you passed the mock 38% is regarded as a D.... also anyone doing applied electricity know the odds of transistors coming up?

I can see that Boyle's law and the monochromatic light are likely to come up, but are there any other predictions that might come up? Thanks

Joule's Law
Speed of Sound
Conservation of Momentum
Variation of Frequency of a String with Length
Variation of I with V diode/copper sulfate/bulb/metallic conductor

^^Thank you!!!

For particle physics is it only me or is every scientist's name associated with it hilarious?

Gellman
Cockroft
Ernest
Zweig

Millikman deserves a mention too.

How can people find it hard learning all the names anyway. Well it's easy for me anyway because I try to picture names so they stick

DM360

I'd say they'll ask for who discovered or who predicted the neutrino, hasn't come up for a while has it? If the particle physics is about the neutrino it would be lovely

And just to say, his name's a much less humorous Millikan, not Millikman

Don't be panicking guys, physics ain't that bad. Our teacher said you should know your expts inside-out and you've then got 30%, then section B...Q5 and Q12 are very doable and then pick 3 more of your preferred Qs from the remaining 6 and some parts you can pick up very handy marks.

So that'd be 120 marks from section A, 56 from Q5, maybe 40 from Q12 then at least 25 from the other 3 Qs.....that's a lot of marks....everyone has their own aims though

Best of luck everyone

This, not to mention the amount of experiments that you can backwards engineer from the relevant formulae's in the tables book.

We should petition the SEC to rename the book "The Physics Tables". . . I reckon I have used over 60% of it's content for physics purposes in the past 2 years. ..

It was actually Wolfgang Pauli who proposed the idea and it wasn't detected experimentally until 1956 by Cowan and Reines.

What did Fermi do?

I know, I meant Millikan was the name instead of Millikman, it wasn't the answer.

And also Fermi named the neutrino

Well I'm freaking out right now I know I shouldn't be but I'm worried about a good chunk of it.
I don't know half of electricity, half of modern physics or magnetism. I'm good for everything else except them. I'm slightly tempted to get up at 5.30 and cram modern and particle physics so I'll have two questions covered for sure.

im gettin up at 5 to cram experiments though =(

I don't know any of the electricity ones. But I'm fairly confident on the others because my fifth year teacher hammered them into our heads.
The more I think of getting up early the less I want to do it

So anybody doing applied electricity? Our class seems to be alone...

Most teachers hate it!

The first year of the new course most teachers did the Applied Electricity because it was on the old course and Modern Physics wasn't. That year the average marks on Applied Electricity were 30% (90% of the physics population did it) while the Modern Physics was much better answered. From then on my teacher taught Modern Physics..

True story..! :P

Probably true. . .sorry. . .

About 1.2% of people answering this question(open to correction on this) did the year the Chief Examiners report was out. . .thats a maximum of about 60 people. . .and more likely about 40 people, as not everyone answers the option. . .

ride-the-spiral

I dunno, I quite like it. I tried to do the particle physics myself as a back up but there's too much of just learning it for me, so I prefer the understanding part of the AE. And also, a lot of it just reiterates the previous electricity chapter's so it reinforces your understanding of it.

I know this is for HL but I really need this question asked about OL. Has heat come up every second year since the course the started (excluding Q1-5)? It looks that way but I want to be sure. I sure hope that isn't the case because I find that the easiest topic on the course.
