In this Science 101: What is X-ray Light video, scientists Jessica McChesney and Gilberto Fabbris explain what X-ray light is, and how they use it at Argonne’s Advanced Photon Source (APS). X-ray light is high-energy light that exists on the electromagnetic spectrum. This spectrum includ...
yield is the ratio of fluorescence X-rays to incident X-rays. The diagram below illustrates the K and L fluorescence yield as a function of atomic number, Z. It is clear that the yield for the light elements is very low, and this is reflected in achievable sensitivity for these elements...
In this paper we explore the X-ray emission and light curves of all known supernovae (SNe), in order to study the nature of the medium into which they are expanding. In particular, we wish to investigate whether young SNe are expanding into a steady wind medium, as is most often ...
What is an X-ray laser?Question:What is an X-ray laser?Lasers:Lasers are optical devices that produce coherent beams of light by stimulating a gain medium. The excited electrons of the medium produce photons of a specific wavelength which means that all the light produced has the same wavele...
eg. the light we see, UV (ultraviolet)what we use in remote controles for the tv. x-rays and gamma-rays are the only on the side that causes cancer. Additional info: mobile phones are believed to cause cancer. this is not certain yet. mobiles use microwaves that are not on the ...
The red light means “Stop”. 红灯表示停止。 I mean to go shopping. 我的意思是去购物。 The sign means that the road is blocked. 这个标志表示此路不通。 (2)mean的名词形式是“meaning”,表示“意思、含义”。例如: ...

which represent binary information. when the cd player's laser shines on the surface of the disc, it reflects differently depending on whether it hits a pit or a land. this reflected light is then converted into electrical signals that can be interpreted as audio or other types of data. wh...
