Wilhelm Roentgen's discovery of X-rays contributed to our understanding of the atom by allowing scientists to study the internal structure of atoms, theorize that x-rays are capable of knocking electrons loose from atoms.

Wilhelm Roentgen discovered a type of radiation which he called X-radiation.

Wilhelm Roentgen's discovery of X-rays revolutionized the field of medicine and earned him the first Noble Prize in Physical in 1901.

One practical application of Wilhelm Roentgen's discovery of X-rays is in medical imaging, such as X-ray radiography. This technique allows doctors to see inside the body and diagnose various conditions.

Roentgen reported the discovery of X-rays in December 1895, after seven weeks of careful work he studied the properties of this new type of radiation able to go through screens of notable thickness. He named them X-rays to underline the fact that their nature was unknown.
