Most of us know how important the Class 12 board examination marks are in building a lucrative career. This year, the annual board examinations started on March 5, 2018 and would go on till April, 13.
Students who wish to pursue a career in the science related stream will agree that the score in Physics subject is extremely important, however, one can't deny that the Physics is one of the scoring subjects.
Every Class 12 student agrees that the Physics is one such subject which requires confidence while answering a question, because the questions are very straight-forward. The best way to gain a perfect score in this non-traditional subject, Physics, is to solve the previous year's question paper along with mastering the important topics. Due to time-constraint or the other reasons, many students might neglect this area.
When the CBSE Class 12 students are all set to take the Physics paper on March 7, they might be juggling with the study notes at this moment. Spare a few minutes with us as we furnish the most important topics you need to revise on this last day.
Topics You Need To Revise On This Last Day
Almost all the chapters and topics in the Physics are equally important, however, after careful analysis of the previous year question papers, we've decided the below topics are the most important. And students are advised to give the prior importance to these areas.
The Columbus law in vector form, Gauss theorem of electric field, electric potential and capacitance of parallel plate capacitor are the topics one need to focus on the last day.
Unit-II (Current Electricity)
Relation between current and velocity, drift velocity, Kirchhoff's laws, parallel connections of resistors and potentiometer are the important topics.
Unit-III (Magnetic Effects of Current and Magnetism)
The application of Biot - Savart law, Ampere's law along with its application, Cyclotron, moving coil-Galvanometer, magnetic dipole moment, properties of magnetic substances and torque on a magnetic dipole (bar magnet) are the areas to focus.
Unit-IV (Electromagnetic Induction and Alternating Current)
The mutual induction and self induction, relation between RMS and peak value of current and resonance in series LCR circuit.
Unit-V (Electromagnetic Waves)
The electromagnetic spectrum, basic concepts of displacement current and properties of EM waves are the important topics.
The total internal reflection, Lensmaker's formula, microscopes and astronomical telescopes, refractive index of a prism, scattering of light and polarisation are the key concepts.
Unit-VII (Dual Nature of Radiation and Matter)
The dual nature of radiation, photoelectric effect, Hertz and Lenard's observations and Einstein's photoelectric effect are the expected topics for this year.
Unit-VIII (Atoms and Nuclei)
The Bohr model, hydrogen spectrum, alpha-particle scattering experiment, mass defect and nuclear fission & nuclear fusion.
Unit-IX (Electronic Devices)
The energy bands in conductors, junction transistor, diode as a rectifier and semiconductor diode.
Unit-X (Communication System)
The basic concepts of communication system, types of modulation, propagation of electromagnetic waves in the atmosphere and modulation index.
