Little wanderers from Harsukh
A community of artists, thinkers, and organic farmers, Harsukh Idara-e-Ilm o Funn at Bedian, graced Physlab with the presence of their little wonders from six grade. School kids, at the tender age of around 12, but filled with excitement and vigor turned into active physicists exploring the realms of mother nature. The Harsukh students jubilantly participated […]

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. […]
