(C)25.What are the X-rays?相关知识点: 试题来源: 解析 X射线是一种电磁辐射,其波长介于紫外线和伽马射线之间。X射线具有很强的穿透力,能够穿透许多可见光无法穿透的物质,如肌肉和软组织,但会被密度较高的物质(如骨骼和金属)吸收。这一特性使得X射线在医学诊断中得到了广泛应用。 X射线是一种电磁辐射,其...
X-raysModern ViewX-ray ScienceFew problems in physics have received more attention than the complex nature of light. The historical roller coaster of its description dates back to Huygens and Newton around 1700 and seemed to have been resolved by Young and Fresnel around 1800 in favor of the ...

Rays have a flattened body shape and an elongated tail. The pectoral fins are large and connected to the body to form the ray’s “disc.” The shape of the disc differs from species to species and may be circular, oval, wedge-shaped or triangular. Some body shapes are adapted for livin...

Although the term "x-rays" was only meant to be a placeholder, the name stuck, much to Röntgen's chagrin. In some languages, these rays are actually referred to as Röntgen rays. His landmark paper in the field was titled "On a New Kind of Radiation." Because of the tiny ...
(UV) light and gamma-rays. Hard X-rays have wavelengths of about 100 picometers (a picometer is one-trillionth of a meter). These electromagnetic waves occupy the same region of the EM spectrum as gamma-rays. The only difference between them is their source: X-rays are produced by ...
THIS little book gives a fascinating account of cosmic ray research, its results and its unsolved problems ; the book is, indeed, an outstandingly attractive work on science for the non-specialist, and should appeal to the educated public that in recent years has so eagerly welcomed accounts ...
