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 […]
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.
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 […]
