So in photoelectric effect, electrons can be ejected from a material when a beam of light shines upon the material, provided that the incident photons have enough energy to overcome the work function, i.e. hbar*omega has to be greater than W. Now, why can't I have n photons simultaneously...

Hi guys, Last term I joined the research group of one of the professors in my university, and I did a one-semester research project with him. He offered me to continue on with the project and with his group for my final year thesis, but I think I do not want to. This is because I have decided...

My suggestion is, if you love physics, work hard for it. Use this summer to prepare ahead for the courses you will take next semester. It is all about hardwork and practice.

That's a question no one knows the answer to.

Yes, I guess you have to. Everything becomes more and more bizarre as you progress. Oscillating EM field gives off light, which is something physical, it is not purely mathematical anymore.

It is still best to do it if that is the first time you see such integrals.

Dont forget to include your contacts as well, include phone no., email, address, etc. What is 'lab techniques' and 'vibration' under coursework? Better omit that or state the title of your course, e.g. experimental physics. I suggest putting in a section for "career objective" as well. And...

Mass is a measure of inertia, and so is momentum. See http://en.wikipedia.org/wiki/Inertia For me, I think inertia is a concept invented just to explain the concept of mass and momentum.

Well maybe you still can go to accelerator physics. Why not you go and search for it on the web? See what they look for in an experimental accelerator physicist. Or wait for someone working in/ familiar with that field to reply here.

In my opinion, knowledge in electronics will be a great asset to work in CERN, but as the engineer, and not as the physicist.

IOP also has a very good career section: http://www.iop.org/careers/index.html

I thought I should share in case anyone don't know TedEd yet: http://www.youtube.com/user/TEDEducation

According to string theory: everything is made of vibrating strings.

How does writing a laboratory report concern real-life applications? That is an interesting question to ask but normally you won't bother with that when writing a laboratory report.

Now, now, I think the definition of weight is mixed up here with layman language. As I was taught, weight in physics is a vector, its SI unit is Newton. In layman use, weight normally refers to the scalar quantity that we call mass in physics, and the SI unit is gram.
