Answer & Solution
Correct Answer
(B) X-rays
Step-by-step Solution
Detailed explanation
Wilhelm Roentgen, or W K Roentgen Professor of Physics in Wurzburg, Bavaria, discovered X-rays in 1895—accidentally—while testing whether cathode rays could pass through glass. X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with…
