A Simple Method of Demonstration of Characteristics of Rainbows Using a Glass of Water and a Few Laser Sources
Soumen Sarkar, Sanjoy Kumar Pal, Pradipta Panchadhyayee +2
A rainbow is a captivating natural phenomenon resulting from the refraction, dispersion, and reflection of sunlight within water droplets. Traditional classroom demonstrations ofte…
Use of smartphone as a density measuring device
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
In this paper, we have proposed a simple method of measuring the density of a solid material. We have utilized the pressure sensor of a smartphone as a pressure-measuring device. B…
A smartphone-based simple method for determination of the free space permeability
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
A simple and novel method is designed to determine the free space permeability. This value is computed from the expression of the terminal velocity of a magnet falling through a co…
Determination of the acceleration due to gravity by studying magnet s motion through a conducting pipe
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee
We determine the acceleration due to gravity (g) in a novel way using a magnetic sensor and video analysis technique of a smartphone. The same applications are used to measure the…
Study of the effect of electromagnetic damping force on a magnet oscillating near a non-ferromagnetic conducting plate
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee +1
We have designed an experiment that involves studying the effects of a conducting plate on the motion of an oscillating disc magnet. We have employed the video analysis method by T…
