frequency for hard xray value
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
The 'soft' and 'hard' refer to the energy of the x-rays used to perform the spectroscopy. Hard x-rays are higher energy x-rays than soft x-rays. Where to draw the line for when an x-ray stops being 'hard' and becomes 'soft' is rather arbitrary but most people would agree I think that x-rays of energy ~ 1500 eV and less are 'soft' x-rays and above ~ 2500 eV are 'hard' x-rays.
Hard x-rays have wavelengths below 0.2nm-0.1nm .Soft X rays have wavelengths above.
The difference between a hard x-ray and a soft x-ray is the amount of energy that they both use. Hard x-rays are used to see the inside of the human body. Soft x-rays are not used often because they omit a lot of radiation.
X-Rays are electromagnetic waves with a high frequency (lying between UV radiation and gamma radiation on the EM spectrum) and as a result, have a very small wavelength (on the atomic level). Because of this high frequency, they carry high amounts of energy, and have a high penetrating power. X-Rays are ionising, meaning they can cause cancer in humans if exposure is high enough. The two main types are "hard" X-Rays and "soft" X-Rays. The differences are, "ard" X-Rays have a higher frequency, lower wavelength, carry more energy and have a higher penetrating power then "soft" X-Rays. In an X-Ray machine, an aluminium filter is often used to block the "soft" X-Rays, as they are more easily absorbed by the patient and are more dangerous because of this. Resource: HSC Physics course
Electromagnetic radiation is characterised by its frequency. Frequency is measured in Hertz, abbreviated Hz. To a radio man 'high frequency' is in the range 2MHz to 30 MHz. Other e-m radiation is listed below, lowest frequency first VHF UHF Microwaves Millimeter waves Infrared Visible Light Ultraviolet Soft X-rays Hard X-rays Gamma rays.
Soft tissue such as muscle, fat and internal organs is hard to image using X-rays. This is because X-rays penetrate soft tissue relatively easily.
Gamma Rays. Followed by Hard X-Rays, then soft x-rays, then extreme ultraviolet, then ultraviolet, then near ultraviolet, then our visible light comes in. Followed by Near infared and so on.
Because soft x-rays are not as penetrative as hard x-rays they are considered more dangerous as not all the radiation passes straight through the body. Radiation is considered harmful to newly dividing cells. Examples of soft x-rays are dental x-rays and mammograms.
