Principles of X-ray Diffraction Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which correspond in the electromagnetic spectrum with the wavelength of x-rays having photon energies between 3 and 8 keV. Accordingly‚ phenomena like constructive and destructive interference should become observable

less acknowledged—techniques is crystal healing. Crystal healing is a brand of alternative medicine that involves specific crystals being placed on specific parts of the body. These specific placements are because the crystals correspond to chakras that allow the body of the treated person to have accelerated healing. There are a large amount of healers who currently use this technique to treat their patients today. There are many cases where the patients of crystal healers have improved their condition

A Crystal Clear Reflection of Reality In the middle of the billions of people in this planet‚ we are made. In the middle of the widest plain in our world‚ we are found. Why? It is because of the existence our so-called purpose. It was the day the world had a glimpse of another blessing from God. It is not a matter of logical thinking but spiritually speaking‚ we are also made because of God’s purpose. We came into this world with an unknown future waiting for us. Just like what

Why Stuff Expands There is a reasonable explanation to the question of why water expands both when heated and cooled. Not only is the explanation reasonable‚ but the effects of this odd property have their own advantages and disadvantages as well. This process of expansion by cooling starts when the water temperature nears 4° C. The hydrogen atoms begin to line up into neat rows of six molecules‚ but the water retains the same density‚ except for the slight drop that is common with most matter

Minerals possess a number of properties that are used as an aid in their identification just like color‚ luster‚ streak‚ cleavage‚ hardness‚ specific gravity‚ and even by their chemical properties‚ composition‚ Hardness‚ Crystal Form‚ Electrical Properties and Melting Points.
