Body centred cubic
In addition to the particles at the corner of the cube, there is one present at the body centre position of the unit cell. Another type of unit cell, called end centered unit cell, is possible for orthorhombic and monoclinic crystal types. In an end cen..

We know, for a bcc structure..
Face centered cubic
A face centered cubic unit cell has one atom at each corner and one atom at each face center, being shared by two unit cells and making a Hence, a face centered cubic unit cell has,..
Calculation of Density of a Cubic Crystal from its Edge Length
Calculation of Density of a Cubic Crystal from its Edge Length. The edge length of a cubic crystal can be obtained from X-ray studies and knowing the crystal structure possessed by it so that the number of particles per unit cell are known, the ..
The Seven Crystal System
The Seven Crystal System - Crystals along with suitable examples are listed in the table. System Axial distances Axial angles Examples Cubic a = b = c α = β = γ = 90° NaCl,KCl, Diamond, Cu, Ag Tetragonal a = b ≠ c α = β = γ = 90..
Simple cubic
In this type of unit cell, there are eight atoms at the corners and each such atom make..
Calculation of Number of Particles per Unit Cell of a Cubic Crystal System
Keeping the following points in mind we can calculate the number of atoms in a unit cell. * An atom at the corner is shared by eight unit cells. Hence an atom at the corner contributes 1/8 to the unit cell * An atom at the face is a shared by two unit cells Contribution of each atom..
End Correction
There is a difference between the reflection of the wave at the closed end and at the open end. At the closed end, the reflection occurs exactly at that end and therefore, the node will be situated on the surface of water. At the open end of the tu..

I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
Outstanding--the instructor let me do the problem with minimal interruption until I was finished and he helped me identify any errors--wonderful. Thank you tutor vista
Hard work will pay im confident to go ahead and focus on my studies with help of Tutor Vista
Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
