What is the principle of the electron diffractionof graphite?
The principle of electron diffraction of graphite involves using a beam of electrons to interact with the crystal lattice of graphite. When the electrons hit the lattice, they diffract, producing a pattern that can be used to determine the crystal structure of graphite. By analyzing the diffraction pattern, information about the arrangement of carbon atoms in the graphite crystal lattice can be obtained.
Is it possible to use a beam of electromagnetic waves as a killer of terrorists. A satellite fitted with source of electromagnetic waves may be given lat-long of that terrorist to hit?
no, beam weapons are highly impractical in the atmosphere. there is too much distortion, absorption, and scattering.
In what part of the atmosphere does solar particles hit atoms and cause them to glow?
In the very highest layer of the atmosphere, the ionosphere, solar particles collide with oxygen and nitrogen atoms and green, blue and red light is given off.This light is the http://wiki.answers.com/FAQ/7810
Where do astrophysical neutrinos come from?
They originate from nuclear reactions, such as those that take place in a star, when cosmic rays hit atoms and in supernovae.
How do lasers burn things?
In short, Light Amplification by Stimulated Emission of Radiation. Now, to explain. In a laser, there is something called a MEDIUM. This is where the photons are made. In all substances, there are atoms. In the atoms, there are electrons. The electrons are on orbits around the nucleus of an atom. There are more than one orbiting each atom. The electrons are EXCITED by getting hit by photons. The electrons absorb the energy from the photons they are hit by. To be on a certain orbit, the electron needs to have a certain amount of energy. When an electron is hit by a photon, it GAINS ENERGY so is jumps up to another orbit, because it has too much energy to stay on it's normal orbit. The electrons, though, ALWAYS have to go back to their original orbit (a law of physics) and in doing so, it needs to release energy in the form of a photon. Mirrors focus the light and it then comes out of the gun. There are more factors, but they are complicated and I cannot explain them for now. The main thing is the Excitation of the electrons then the release of the photons.

The dots on a crt are lit up when photon torpedoes strike the phosphorous coating on the inside of the tube?
No. It is when the coating is hit by electrons in a focused electron beam.
What controls the point of impact of an electron beam?
The point of impact of an electron beam is controlled by electromagnetic fields generated by focusing elements such as lenses or magnets. These elements manipulate the trajectory of the electrons to ensure they hit the desired spot on a target material. The strength and configuration of these fields determine the accuracy and precision of the impact point.
Why does the resistance of a conductor rise with the rise in temperature?
For metals, as the temperature rises, the atoms wiggle around more, and are more likely to be hit by an electron that is moving through the metal. The more electrons that hit the atoms, the greater the resistance. Think of the wiggling atoms as interfering with the smooth flow of electrons.
Why scanning electron microscope must operate in vacuum?
A scanning electron microscope (or SEM) doesn't use photons (light) to create an image, it uses electrons. Electrons have a much smaller wavelength than photons do, so this allows them to "see" smaller details in an object than a photon can. Unfortunately, electrons are also a lot bigger, so when travelling through air, they are more likely to crash into air molecules and get sent off course. Obviously, if the electrons can't travel in a straight line, they can't be used to make a nice image. That's why an SEM needs a very good vacuum to create a good image.
What will happen if ions hits atoms at high speed?
When electrons hit atoms at high speed some of the electrons are knocked away or broken off of the atoms. Once this breakage happens after impact, the atom then becomes a positively charged ion.
Use beam in a sentence?
The cop shined his flashlight so that the beam of light hit the criminal's face.
What happens in the photosystem protein when it is hit by a photon of light?
When a photosystem protein is hit by a photon of light, it excites an electron within the pigment molecules in the protein. This electron is then passed along a series of molecules in the photosystem, creating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH.
What are good things about beam bridge?
They are less likely to be hit by waves Short span beam bridges are very strong.
WHAT HAPPENS IN THE PHOTOSYSTEM 2 protein when it is hit by a photon of light?
In photosystem II, the photon of light is absorbed by a pigment molecule, which causes an electron to become excited. This electron is then passed through a series of electron carrier molecules, creating a flow of electrons used to generate ATP and NADPH during the light-dependent reactions of photosynthesis.
What happens when light strikes a mirror?
When light strikes a mirror, it is reflected back at the same angle it hit the mirror, following the law of reflection. The angle of incidence (the angle at which the light beam strikes the mirror) is equal to the angle of reflection (the angle at which the light beam bounces off the mirror).
Can a scientist observe living things under an electron microscope?
No, electron microscopes require specimens to be in a vacuum chamber, which is not compatible with living organisms that need to be in a natural environment to survive. Instead, scientists typically use light microscopes to observe living organisms.
