What Are X-rays? X-rays are waves of electromagnetic energy. They behave in much the same way as light rays, but at much shorter wavelengths. When directed at a target, X-rays can often pass through the substance uninterrupted, especially when it is of low density. Higher density targets...
Why do x-ray technicians use lead aprons when they are exposed to x-rays while we are exposed to radio waves and are not protected? 1) Which of the following statements about X rays is incorrect? A) x rays darken photographic plates B) x rays can penetrate soft body tissue C) the ki...
What type of waves are set up in fluids?Wave:In the context of wave optics, the wave can defined as the type of distribution by which only energy transfers from one source to another. By wave, there is no transfer of mass. There are two types of waves in the universe; one is ...
It's a kind of energy called "electromagnetic (EM) radiation" (but this kind of radiation is not harmful, except for an occasional sunburn). There are other kinds of EM radiation too (radio waves, microwaves, x-rays, etc.), but light is the part WE can see, the part that makes the...
I recently returned from the 2025 Annual Meeting of the “Localization of Waves” collaboration (supported by the Simons Foundation, with additional related support from the NSF), where I learned (from Svitlana Mayboroda, the director of the collaboration as well as one of the principal investigato...

500 degrees Fahrenheit. This intense heat is primarily due to the absorption of high-energy X-rays and ultraviolet (UV) radiation from the Sun. However, because the gas molecules are so dispersed, there isn’t enough density for this heat to be felt in the same way it would be at lower...
Radiofrequency ablation uses radio waves to heat the tumor and destroy cancer cells. Radiation therapy uses x-rays to kill or shrink cancer cells. The two types of radiation therapy are external beam radiation therapy and brachytherapy. Chemotherapy is medicine to kill cancer cells and stop it ...
Some gravitational waves are emitted from events that do not produce light. These events are not witnessed by traditional astronomy because traditional astronomy depends on light signals. With gravitational wave detection, we get a whole new perspective of the universe and the kind of objects that ...
X-ray Often x-rays or X-rays A narrow beam of such photons. X-rays are used for their penetrating power in radiography, radiology, radiotherapy, and scientific research. Also called roentgen ray. Ultrasound The use of ultrasonic waves for diagnostic or therapeutic purposes, specifically to image...
