Simple cubic and body centred cubic
In SC unit cell, the atoms inhabit only the corners. In BCC unit cell, the atoms occupy the corners as well as the body centre of the unit cell. In FCC unit cell, the atoms occupy the corners as well as the face centre of the unit cell. In the case of hexagonal closed packed (HCP) structure, atoms occupy the 12 corners, the centre of the bottom and top faces and the body centre of the alternative one sixth of the unit cell. The atoms available at the corners and in the face centres are shared by more than one unit cells. Only the atoms there well within the unit cell solely belong to the unit cell.
Refractive Index: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing single medium to another medium. This constant is
Q. Write the equation of a 25 cycle current sine wave having rms value of 30 A. Data: ν = 25 Hz, Irms = 30 A Solution: i = I o sin ωt =
Explain about the total internal reflection. Total internal reflection: While light is incident onto a medium of lesser index of refraction, ray is bent ahead of the norma
The mass of a mol of proton and electron is: (1) 6.023x 10 23 g (2) 1.008g and 0.55mg (3) 9.1x 10 -28 kg (4) 2gm Ans: (2) 1.008g and 0.55mg

Q. Define: grating element. The combined width of a slit as well as a ruling in a plane diffraction grating is called as a grating element.
A rectangular surface (0.14 m x 0.39 m) is oriented in a uniform electric field of 440 N/C. What is the maximum possible electric flux through the surface?
