If d is the inter-planar spacing of the planes {h k I}, the inter-planar spacing of the planes {nh nk nl}, n being an interger, is

Correct Answer: $$\frac{d}{n}$$

A spacing ‘’D’’ can be used to completely accommodate the lattice misfit in the one direction without any long-range strain field by a set of edge location. Calculate the value of D if the interplanar spacing’s of matching planes are given as 20mm, 19mm respectively? (Assume the misfit to be very small)

The interplanar spacing of (220) planes of a FCC structure is 1.7458 Å. Calculate the lattice constant.

Assume that 5mm and 5mm are the unstressed interplanar spacing’s of matching planes in the α and ß phases respectively, the disregistry, or misfit between the two lattices (∆) is defined by__

Minimum interplanar spacing required for Bragg’s diffraction is:

For an FCC metal, the ratio of interplanar spacing obtained from the first two peaks of the X-ray diffraction pattern is

What are the reasons due to which a person could be considered unfit for registration in the electoral roll?
1. Being an Indian citizen
2. Being of unsound mind and standing declared as such by a competent court
3. Disqualified from voting for the time being under the provisions of any law relating to corrupt practices and other offences in connection with elections
4. Being less than 18 years of age
5. Being ordinarily resident of a constituency

The growth rate of pearlite, v, and the interlamellar spacing S are given by the following relation, $$v = k.\frac{1}{S}\left( {\frac{{1 - {S_c}}}{S}} \right)$$    where Sc is the critical spacing at which the growth rate is zero and k is a materials constant. The actual interlamellar spacing observed will correspond to

The sum of 6 consecutive odd integers exceeds twice the biggest interger by 38. Find sum of the six numbers.

An object is kept in one of the quadrants of principal planes of projection, for both the front view and top view of the object the object came first and then the views on planes (the observer is at top right side of principal planes). The object is in which quadrant?

Before a battle the ratio of tanks to planes in an army was 5 : 3. During the war 1000 tanks were destroyed and 800 planes were destroyed. The ratio oftanks to planes became 2 : 1. What is the number of tanks after the war.
