Today Google is showing a Doodle representing 115th anniversary of the X-ray.
X-rays are very small and energetic. They are produced by accelerating electrons at a metal target. X-rays are used in various medical applications, especially for imaging. And, they are used in scanning Traveler luggage also.
X-ray was discovered by Wilhelm Conrad Rontgen in 1895.
He discovered it accidentally while investigating Cathode Rays using Crookes tubes
Rontgen called them as X-rays to mean that those Rays are unknown.
Röntgen discovered X-ray's medical use when he saw a picture of his wife's hand on a photographic plate formed due to X-rays. His wife's hand's photograph was the first ever photograph of a human body part using X-rays.
X-ray is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometer
X- rays are called as Rontgen rays in many languages, including German and Russian.
Röntgen received the first Nobel Prize in Physics for his discovery.
Röntgen had his lab notes burned after his death.
Lead is the most common shield against X-rays because of its high density , stopping power, ease of installation and low cost.
And, Today's Doodle reminds past April Fools jokes about the idea of "PigeonRank", where the ordering of pages would be determined by pigeon pecks.
