Reflection of Light

Reflection of Light : There are some surfaces which have ability to send the light back in the same medium when light strikes it. This 9. phenomena of sending the light back in the same medium by a surface is called reflection of light.
(i) The incident ray, the reflected ray and the normal at the point of incidence, all lie in a same plane.
(ii) The angle of incidence is always equal to the angle of reflection, ∠i = ∠r.

Semiconductors and Communication System

This chapter can be divided into following categories:- Classification Types of Semi-Conductors p-n junction diode Biasing of Diode Rectifiers Special Diodes (Zener, Photodiode, LED and Solar Cell) Transistors Logic Gates Communication System In the next few posts I will be posting in the same manner ie. (in bullets form) for your convenience and I hope that helps you in completing your syllabus. Classification Materials can be classified on the basis of conductivity as Conductors, Insulators and Semi Conductors. The basic difference among all the three is the difference of energy in between the Conducting and the Valence band. This can be seen here. Note- The range of conductivity should be kept in mind. For Semi-Conductors the energy difference is not very large but not even very less. So by providing proper conditions they can show conductivity. Types of Semi-Conductors Further we can say that there are two other types of semi con...

Limitations of Mendeleev's Periodic Table

Mendeleev arranged 63 elements known at that time in the periodic table. According to Mendeleev “the properties of the elements are a periodic function of their atomic masses.” The table consists of eight vertical column called ‘groups’ and horizontal rows called ‘periods’ Limitations of mendeleev’s classification : (i) He could not assign a correct position of hydrogen in his periodic table, as the properties of hydrogen resembles both with alkali metals as well as with halogens. (ii) The isotopes of the same element will be given different position if atomic number is taken as basis, which will disturb the symmetry of the periodic table. (iii) The atomic masses do not increases in a regular manner in going from one elements to the next. So it was not possible to predict how many elements could be discovered between two elements.
