What are X-Rays?

An electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light.

Everyday Application

How X-rays see through your skin - Ge Wang

Video Summary:

Wilhelm Roentgen was experimenting with a cathode tube ( a vacuum tube containing one or more electro guns and phosphorescent screen used to view images). When experimenting with the Cathode tube he wrapped it with cardboard and turn it on, he then noticed that a screen started to light up. Realizing that the light from the cathode tube was going through the cardboard. He didn't know what this new light was so he called "x-ray" since "x" is used as a variable for an unknown number.

Everyday Applications

-Wavelength range: X-rays are electromagnetic waves with wavelengths in the range of 0.01 to 10


Frequency range : frequencies in the range 30 petahertz to 30 exahertz (3×10 16 Hz to

3×10 19 Hz)

-Velocity in a vacuum: their velocity in a vacuum is the same as visible light:

186,000 miles/second or 300,000 kilometers/sec

-There is a X-ray machines at the airport or a baggage scanner, also to be used to look inside the body to

see broken bones and other things inside of you. And to for historians to check if a painting way painted

over the other one.

NASA's Nuclear Spectroscope Telescope Array, or NuSTAR, has imaged a section of the Andromeda galaxy, which is the biggest galaxy near ours. NuSTAR can pick up even the faintest of these objects. The images were taken by NASA's Galaxy Evolution Explorer in ultraviolet light. NuSTAR is a Small Explorer mission led by the California Institute of Technology in Pasadena. NuSTAR's mission center is at UC Berkeley, with additional support coming from Kenya.
