Hard x-rays have a higher or faster frequency than soft x-rays.
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.
The band of electromagnetic spectrum with the shortest wavelength is the gamma rays. Gamma rays have the highest frequency and carry the most energy of any wave in the electromagnetic spectrum.
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.
