what is x-ray

X-ray belongs in the same category as visible light, radio waves, ultraviolet and microwave. All these are electromagnetic energy. One end of the spectrum has radio waves while the opposite end has gamma rays. Visible light is in the center of the scale. Only visible light can be seen with the eye. Radio waves has a longer wavelength, lower frequencies and lower energy than gamma rays. The gamma rays have short wavelengths, high frequency and high energy. X-Ray is on the gamma ray end. “Because of their short wave length, x-ray can penetrate materials that normally reflect or absorb visible light. Like light, x-rays can produce a visible image on photographic film
