1.	What is the lower range of wavelength of the X-rays?(a) 40 x 10^-7 cm(b) 40 x 10^-8 cm(c) 40 x 10^-9 cm(d) 40 x 10^-10 cmThis question was addressed to me during an online interview.My query is from Radiography topic in section Non Destructive Techniques of Casting-Forming-Welding II
Answer» Right choice is (B) 40 x 10^-8 cm To explain: The X-RAYS are considered to be rays having a SHORT wavelength. These X-rays can be PRODUCED with the help of an X-ray tube or a Cobalt-60 isotope. The longest wavelength of an X-ray is 40 x 10^-8 cm.
