Peter Higgs comes to Oxford!

My Life as Boson

Friday 16^th May 2014, 4:30-5:30pm

Professor Peter Higgs, Professor Emeritus, University of Edinburgh comes to Oxford to talk about his work. Online registration for this event is required, register online here. The lecture will be held in the Andrew Wiles Building, Mathematical Institute (fully booked). There will also be a mixed live stream of the lecture to the Martin Wood Lecture Theatre and the Lindemann Lecture Theatre in the Clarendon Laboratory. A drinks reception will follow on both sites. 

TP questions

1.Give one reason why Huygens’ wave theory of light did not replace Newton’s theory of light when the fringe pattern due to double slits was first observed. (1)

2.The interference fringe pattern observed by M’n’M on their interferometer did not shift when the apparatus was rotated by 90°. Explain the significance of this null observation. (1)

3.   Discuss the significance of Einstein’s explanation of the photoelectric effect. (2)

4.   Millikan found that the charge on an oil droplet was always in multiples of e. Explain the significance of this result. (1)

5.   What was the significance of Thompson’s calculations of the specific charge of an electron? (2)

Microscopes HW

•You need to have an understanding of the working of the transmission electron microscope and the scanning tunnelling microscope

•Use the black books/ the internet to compare the workings of these two  types with the traditional light microscope.

•Use headings such as; source of rays, transmission of rays, how image is focussed, how image is produced, resolution, specimen preparation  

Relativity HW

What is the evidence for mass-energy equivalence?  Bring to next lesson ready to discuss.

ISA resits for Y12 ISA Weds 26th P1 and 2

A reminder to Y13 Physicists resitting their Y12 ISA, you need to come to W8 at 8.30am, tomorrow for your ISA which will take place during P1 and 2.
Thanks
Ms Hamnett

Work for Y13

Dear Y13
Sorry for missing the lesson yesterday.  Your papers are available to collect from Dr Pontecorvi's room, please come and find him or me to collect your paper tomorrow. 
Work set for this week;

• Check through your paper and correct your 3 worst questions on the long answer paper.
• Write a perfect answer for Q3 (long answer q)
• 13b and Ayman- do a "if only I'd known" analysis for each question - what would have gained you marks if you had remembered, or done it right? 
• Set yourself a target task arising from this which you will do over the next two weeks
• ALL - Research Millikan's oil drop experiment - what did he do, outline the experiment and it was s significant "turning point" in Physics

Thanks and sorry again
Ms H
