Description and Objectives:

The course titled Modern Physics Labis intended for students enrolling for B.S Degree in Physics. The main objective of this course is to study and measure different physical phenomenon experimentally using different devices. Almost half of experiments related to optics in which we study experimentally different phenomenon of light e.g. reflection, refraction, dispersion, diffraction, and interference using different optical instruments like Spectrometer, Michelson Interferometer, Photo diodes etc., and on the basis of these studies determine the different optical parameters e.g. wavelength of light, refractive index of glass material, Cauchy constant etc. While remaining experiments are related to other different fields of Modern physics like semiconductor electronics, Radio frequency measurements, nuclear physics and atomic physics etc. With these experiments students will be able to learn how semiconductor solar cell works, what are the parameters which can increase their efficiency. Radiofrequency response of RLC acceptor and rejecters circuits, their characteristics and applications e.g. in devices which work with radio frequencies waves, radioactive radiation detection using Geiger Muller Tube, radiation shielding and analysis and calculating fundamental parameters of subatomic particles e.g., charge to mass ratio of an electron.
