Question

Name the high energetic invisible electromagnetic wave which helps in the study of structure of crystals.

• A. $X$-rays
• B. Cathod rays
• C. Gamma rays
• D. All of the above

Answer 1

The correct option is A $X$-rays

The electromagnetic wave which helps in the study of structure of crystals is X-rays.
If a beam of x rays is passed through a crystal, it makes a pattern on a photographic plate. The pattern is called crystallogram (the arrangement of the atoms each crystal has its own crystallogram). It reveals the crystal`s internal structure.
