Introduction The electromagnet is a combination of two words electro + magnet. The second one is clear, this is the magnet but what about first (electro)? What does it indicate electron or electricity? Let me know about, just think? Yes, it is electricity that flows […]
Planck’s Constant Experiment Viva Questions: Planck’s Constant using LED Determination of Planck’s constant by using light-emitting diodes (LEDs). APPARATUS: Planck’s constant kit, wires, graph paper, and 3-4 LEDs. FORMULA USED: Planck’s constant is h = eV /ν, where e is an electronic charge, V is […]
Semiconductor Diode Characteristics To determine the V-I Characteristics of a p n junction diode To draw the characteristics means behavior of current in forward and reverse bias of a semiconductor junction diode. This diode either made by silicon or germanium which has atomic number Z=14 or […]
In e/m Thomson Method experiment, we determine the specific charge value e/m ratio by the Thomson method. Cathode ray tube is the main component of this experiment. As you know cathode ray tube has three components first is electron gun second is deflector plates for […]
Michelson Morley experiment (the Main topic starts after 9:00 minutes, and watch at 33:00 minutes by simulation) In this video lecture, I have started with some basic concepts which are required to understand the topic, whom I say supporting physical concepts by which one can […]
Michelson Morley Interferometer With the help of Michelson Morley Interferometer simulation, I have tried to explain these basic concepts… Rotation of Interferometer Michelson Morley experiment Semisilvered glass plate role the distance of two mirrors from the semi-silvered glass plate and its effect time difference between […]
Introduction Quincke’s Method In this video, I have discussed the calculation of the magnetic susceptibility by using Quincke’s experiment. What are the important points for the measurement of the magnetic susceptibility in Physics Lab in addition to the manual errors: These are; 1. the First […]
