(d) 25 to 15cm

I have been asked this question in my homework.

This question is from Testing Aircraft Materials topic in section Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

Right choice is (b) 10^-6 to 10^-9 cm

For explanation I would say: Different types of rays are classified based on their respective wavelengths. The wavelength bracket in which the rays are considered to fit the category of X-rays is from 10^-6 to 10^-9 centimeters.
