Frequency was 6.0 HZ

Speed was 4.5x10^3

lambda=c/f=4.5x10^3/6.0=750m

Damn it I think I did that but accidentally put 4.5x10^-3 into my calculator! Argh I swear half my lost marks are for being a muppet with the calculator :frown:

Ohh trust me you haven't :smile: it just seems like you're being a bit full of yourself, you sound like one of them posh school kids , whom I hate so very much. And I've been putting my head down hope full marks is round 60.


Full marks will probs 70 :-) like I said, it was not a difficult paper... Absolute beauty of a paper in fact!

I think everyone misunderstood the last question on the paper. It was white light passing through a single slit. Look at the textbook page 202, figure 2. Apparently no one here realized it.
Was this 2 marks??.. if so could you kindly allocate where the marks would be awarded. I use c=flambda , rearranged to make lambda the subject.. but i got 7.5x10^-4.. how did you get 750m from that was the speed not given in m/s?

The highest for 120ums since june09 has been 62 raw marks. I think 120 ums will be 65/70 at max. People doing it for the first time will not have found it as easy as the retakers :wink:
**** ! thats what i did! :redface: how many marks do you think we would lose? considering it was 2 marks? if im correct?

I don't think it will be as high as 65, have you seen the amount of people dropping marks on silly errors! This paper was littered with traps!

You're welcome :smile:

If we're lucky we might get one for rearrange it properly etc, they are generous sometimes. Ah well, whatever happened, happened :wink:

Note I said max :smile:
JUST TO GET PEOPLES ATTENTION !!!

EDIT: It wasn't a easy question.

Exaggeration? :P Natural Sciences (Which I'm applying for) has 4 per place.


Wow, that is a hell of a lot lower. I firmed my Bristol offer for Maths, and that had 14 places per applicant according to their website. I would only assume Oxbridge would be higher.
Perhaps Maths gets more applications?

Yeap I think that would be likely. yeap thats the philosophy, nothing we can do to change the result now! :smile: hope you done well though mate, I need 120 UMS for this hopefully it will be about 61/62 :smile: made a silly mistake on this one though!
