Estimation of the error matrix in a linear least square fit to the data from an experiment performed by smartphone photography
Sanjoy Kumar Pal, Soumen Sarkar, Surajit Chakrabarti
Determination of the Young modulus of a metal bar in the form of a cantilever is an old experimental concept. However, we have taken the advantage of modern advanced technology of…
Use of a smartphone camera to determine the focal length of a thin lens by finding the transverse magnification of the virtual image of an object
Sanjoy Kumar Pal, Soumen Sarkar, Surajit Chakrabarti
In this work we have determined the focal length of a concave lens by photographing the virtual image of an object by a smartphone camera. We have similarly determined the focal le…
Determination of the transverse width and distance of an object with a smartphone camera
Soumen Sarkar, Sanjoy Kumar Pal, Surajit Chakrabarti
A smartphone is a powerful learning aid in the hands of a large section of students around the world. The camera of the phone can be used for several learning purposes apart from i…
Determination of the refractive index of water and glass using smartphone cameras by estimating the apparent depth of an object
Sanjoy Kumar Pal, Soumen sarkar, Surajit Chakrabarti
A smartphone camera can be used for measuring the width and distance of an object by taking its photograph. The focal length of the camera lens can be determined very accurately by…
Determination of the damping co-efficient of electrons in optically transparent glasses at the true resonance frequency in the ultraviolet from an analysis of the Lorentz-Maxwell model of dispersion
Surajit Chakrabarti
The Lorentz-Maxwell model of dispersion of light has been analyzed in this paper to determine the true resonance frequency in the ultraviolet for the electrons in optically transpa…
Observing Doubly Charged Higgs Bosons in Photon-Photon Collisions
Surajit Chakrabarti, Debajyoti Choudhury, Rohini M. Godbole +1
We discuss the possibility of observing doubly charged Higgs bosons in collisions. We find that one can increase the range of observability close to the kinematic limit by a j…
Singlet-Higgs-Boson Signals at Hadron Colliders
Anindya Datta, Amitava Raychaudhuri, Sreerup Raychaudhuri +1
Many extensions of the Standard Model include singlet higgs bosons, , and also vectorlike fermions which couple to it. The production and detection pos…
