Measurements through conical shaped pendulums
A simple experiment using conical shaped pendulums, to see where experiment matches theory. It is customary in practical work to ask when two measurements “match” and when do they “differ”. Furthermore we need to find agreement of experiment with theory. This experiment aims to quantify the similarity (or difference) between various measurements.
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 […]
