Today's x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. ...When x-rays come into contact with our body tissues, they produce an image on a metal film. Soft tissue, such as skin and organs, cannot absorb the high-energy rays,...
The image is formed as a photograph (called an electron micrograph) or as an image on a TV screen.That's the basic, general idea of an electron microscope. But there are actually quite a few different types of electron microscopes and they all work in different ways. The three most famil...
3xx: Indicates that further operations are required 4xx: Client error 5xx: Server error 2) Query the DNS server for the IP address of the web server Before the client sends a request to the server, there is still one more work to be done, which is to query the IP address corresponding...
These radioactive atoms are formed by bombarding normal chemicals with neutrons to create short-lived radioactive isotopes. PET detects the gamma rays given off at the site where a positron emitted from the radioactive substance collides with an electron in the tissue (Figure 1). In a PET ...
Electromagnetic waves in some form or fashion are focused onto the specimen to allow its details to be observed. Magnification, resolution, and contrast have to work together to achieve the best possible image. If you're also interested in reading about how the study of microscopy evolved then ...
Two of these methods are among scientific theories about how lodestone forms in nature. Some scientists speculate magnetite becomes magnetic when struck by lightning. Others theorize that pieces of magnetite became magnets when Earth was first formed. The domains aligned with Earth's magnetic field wh...
Evanescent waves are associated with imaginary wave vector components. Total internal reflection occurs when the magnitude of the wave vector in air is smaller
How are electromagnetic waves like ocean waves? What makes a wave transverse and a wave longitudinal? Is it possible to make a sound wave transverse? Are shear waves transverse waves? How are electromagnetic waves generated? How do surface waves travel? How are Rayleigh waves formed? How do yo...
