This is a two-semester long laboratory course for the second year BS-MS students. The course aims to give the students hands-on experience with experiments of modern physics, electrical, electronics and optics. The experiments are divided in three categories (a) Modern Physics: Selected experiments of modern physics to observe and understand phenomena whose discoveries led to major advances in physics, covering principles and origins of Quantum Mechanics, quantum structure of atoms, concept of wave particle duality and so forth; (b) Electrical and Electronics: The experiments cover basic laws of electrical phenomena and principles of semiconductor devices like transistors and diodes; (b) Optics: Experimental observation, understanding / interpretation of basic phenomena of light such as interference, diffraction and polarization.
- Modern Physics: Experiments involving determination of Plancks constant, study of atomic levels, electron diffraction, basic measurements and concepts in quantum mechanics, verification of the black body radiation law, measurement of elementary electric charge.
- Electrical and Electronics: Practical usage of basic electrical / electronic components, voltage, current, resistance, and power measuring instruments, oscilloscope, signal generators etc. Experiments on diodes, rectifiers, transistors and measuring their characteristics.
- Optics: The experiments cover concepts on fundamental properties of light (EM) wave and some basic phenomena associated with light matter interactions. The experiments involve- determination of wavelength / frequency, velocity of light; observation / understanding interference and diffraction phenomena concept of coherence of light; measurements of polarization characteristics of light and polarizing interactions with matter.
- Along with the lab work, there will be lectures covering statistics (error analysis), data analysis, and physics behind some of the detectors and sensors used in the experiments.
