Step I: Identify the peaks and their proper 2Θ values. Here are the typical eight 2Θ-value entry fields provided with this interface. You can increase or delete rows for data elements depending upon the test X-ray pattern. Also choose the relevant wavelength of X-ray source.
 
Q 01: X-rays can be deflected by:
  • (A) Electric Field
  • (B) Magnetic Field
  • (C) Electromagnetic Field
  • (D) None of the fields
