Electromagnetic Radiation - waves of energy generated by the acceleration of charges

 

 

Why can't neutrons make this kind of wave?

 

 

Have no charge

 

- travel at the speed of light in a vacuum

Charges "shake" off their energy

 

 in waves when they vibrate

Conversion of a DICOM-format X-ray from a ten year old male showing polydactyly. This is the patient's left hand, posterior-anterior projection. Identifying tags and such have been stripped. en:User:Drgnu23, subsequently altered by Grendelkhan, Raul654, and Solipsist.

 

 

In the late 40's & early
50's, an x-ray unit was
a common shoe store
sales promotion device.
They were finally
banned in the US in 1970.
