What are they?
X-ray waves are sort of like visible light, infrared radiation, microwaves, and even radio waves. The difference is that x-ray waves are a lot more energetic! Even only one photon can be hundreds or thousands of times more energetic than one photon from visible light.
How are they created?
X-ray waves are given off by stars, strongly by types of nebula. X-rays are waves of very high frequency, and pass through most substances. X-ray machines work by firing off a beam of electrons, if the electrons have enough energy, and x-ray will be produced.
Why are they created?
X-rays are created to help doctors and scientists in the medical field. Since X-ray waves pass easily through soft tissue, they are often used to look inside things, such as the human body. Have you ever broken any of your bones? If you think you have broken something in your body, you would get an x-ray to check. However, there are multiple uses to X-ray waves such as airport security checks or astronomy.
What are the dangers?
X-rays can cause cell diseases and cancer. Radiographers in hospitals stand behind shields to protect themselves. However, the dose is not enough to put the patient at risk, but can be dangerous if they take many doses each day.
Accurate Example of an X-ray
The wavelength range from .01 to 10 nanometers, corresponding to the frequencies that range from 30 petahertz to 30 exahertz. The energy levels from 100 eV to 100 keV. X-ray wavelengths are longer than UV rays and shorter than Gamma rays.
1. X-ray waves were accidentally discovered by Wilham Conrad Roentgen when he was experimenting with vacuum tubes.
2. The first x-ray was of Roentgen's wife's wedding ring, she was less than impressed.
3. Pregnant women often cannot get x-rays because if the fetus is exposed to the radiation, the greater the chance the child will develop leukemia.
