Video: ATOMS-III

The video ATOMS-I was the first in a series to help you learn the unit ATOMS & NUCLEI. It dealt with Thomson & Rutherford models, their success and drawbacks.
In the video; ATOMS-II explained Bohr’s model of atom.

The video ATOMS-III explains how Bohr’s theory of hydrogen atom successfully describes the discrete nature of radiations. The emission of spectral series of the atom has been explained. The video is another in a series on the unit Atoms & Nuclei from ‘physicsbeckons’ by the author to help you learn Physics without fear.

Videos ATOMS-II

The video ATOMS-I was the first in a series to help you learn the unit ATOMS & NUCLEI. It dealt with Thomson & Rutherford models, their success and drawbacks.

In continuation; the video ATOMS-II deals with Bohr’s model of atom
.
It explains how the theory given by Neil Bohr helps us to successfully derive expressions for orbital radii, speed of the electrons & the energy of the electron in different orbits of hydrogen atom.
The video is another in series from the author to help you learn Physics without fear

Videos-Dual Nature of Matter & Radiation-III

The video titled ‘Dual Nature of Matter & Radiation-I & II’ explains the phenomenon of Photoelectric emission.
The videos are a part of the series of videos aimed at helping the students develop conceptual understanding of the subject & to help in preparation for CBSE examination.
The present video aims at giving the students an idea of how the concepts learnt are applied in solving the problems.
The students are advised to go through the three videos in order i. e. I, II,III & practice sufficient number of problems from CBSE papers to garner confidence required to face the examinations.
The video may be viewed at the link below:

Videos-Dual Nature of Matter & Radiation-II

The video titled ‘Dual Nature of Matter & Radiation-II’ explains the dualistic nature of matter & waves. The video explains de Broglie hypothesis of matter waves; the experimental evidence in favour of the matter waves and their applications.
The next video in this series will cover some numerical & other problems to reinforce learning.
A list of problems for practice in this unit will be separately uploaded.

Supplementary material for AISSCE 2015 Physics issued by CBSE

Dear friends,
CBSE has introduced a few new contemporary topics in the Physics syllabus for 2015 exam (class 12).
The supplementary study material has now been issued by CBSE. It will be useful for the students of class 12 as it will define the limits to which the topics are to be studied.

As the content is new, it is generally expected that questions will be asked from these topic. The topics are simple and easy to understand. Please go through the same carefully.

Please share the material with all students.

Videos-Current Electricity-I

It is a pleasure to present a new project in our effort to make learning Physics easier. In order to give you a feeling of the real Class room teaching learning process, we at physicsbeckons are trying to produce and present the CBSE Physics class 12 curriculum in the form of videos. To begin with, a video on the lesson Current Electricity (Physics) class 12 has been uploaded.

The video Current Electricity-I is an introduction to Electric Current, types of current and a few simple numerical problems based on the content learnt. You may go through the videos carefully to understand the basic concepts involved and the applications thereof for solution of the numerical problems.
Please make sure to reinforce learning by carefully going through any Text/reference book and try more numerical problems in order to gain the confidence and to reassure yourself that the lessons have been well understood.
