An easy method to determine the plane of polarization of a light beam
Many a time, we need to determine the plane of polarization of linearly polarized light. This could simply be the light issued from a laser or emerging from a polarizer. We utilize a simple method which we describe below and demonstrate in the accompanying video. We prepare a solution of 4.5 micron polystyrene microspheres. We […]
Measuring the Surface Tension of Water using the Pendant Drop Method
This experiment involves a simple method to determine the surface tension of a liquid, which in our case is water, by analyzing a drop formed at the edge of a tube containing the liquid. This technique is called the Pendant Drop Method since the liquid drop assumes a pendant shape under the influence of gravity. […]
A first course on contemporary physics by Dr Sabieh Anwar
Our freshmen (first year undergraduate) modern physics course at LUMS is offered to around three hundred students every year. I joyfully teach this course but this time, the challenge was immense. This I took upon myself. I wanted to introduce my students, of course most of them will never study physics again, to what happens in the […]

Synthesis and properties of nickel-doped nanocrystalline barium hexaferrite ceramic materials M-type barium hexaferrite ceramics have emerged as important materials both for technological and commercial applications. However, limited work has been reported regarding the investigation of nanocrystalline Ni-doped barium hexaferrites. In this study, nanocrystalline barium hexaferrite ceramics with the composition BaFe12−xNi x O19 (where x = 0, 0.3 and 0.5) […]
