Physics masters with undergraduate in computer science I am currently entering my third year of undergraduate. When I entered college I was torn between physics and computer science and ultimately chose computer science. I like cs, but I'd like to apply it towards physics applications. I've spent the past two summers working at software companies as an intern, so I have no research experience as of now. I need to start applying for research positions soon if I am to get into graduate school I've heard.

I am wondering if it is possible to get into a masters program for physics with my undergraduate in cs?  My school offers a minor program for physics which covers mechanics, E &amp; M, light/waves/heat, and quantum which I am currently working towards as well. For the research, is it even worth applying to physics labs if my major is computer science or should I stick to applying to cs labs? In a physics lab maybe I could aid in preparing apparatus that involve programming or electronics?
I would say you would absolutely be able to get in to a physics masters program as long as you have taken the pre-requisites for the specific program.  Most programs have a list of courses that must be taken to be considered for admission.

I got my undergraduate degree in Geology and Geophysics, but I became more interested in engineering towards the later part of my undergraduate.  So I was sure to take all of the requisite engineering courses that I needed to get into an engineering masters program.  Now I'm actually working on a PhD in Civil Engineering.  

Moral of the story... It is absolutely possible, but be sure to check out the program requirements for the physics programs you are interested in applying.
