what is the difference between cathode rays and x rays?
534193
Cathode rays are a beam of electrons emerging from the cathode (the negative terminal) within an electron tube. Electrons are actual particles with mass and charge. X-rays are not charged particles but massless electromagnetic radiation.

What is the difference between X-ray and MRI? X-rays use radiation to produce an image of the body's internal structure. ... MRI combines a powerful magnet with radio waves (using no radiation) and a computer to create highly detailed images of structures in the body.

X-rays are a form of electromagnetic radiation similar to radio waves, microwaves, visible light and gamma rays. X-ray photons are highly energetic and have enough energy to break up molecules and hence damage living cells. When X-rays hit a material some are absorbed and others pass through.

Perhaps the most common type of X-ray detector uses an electric current to measure incoming X-rays. In this type of detector, an X-ray interacts with a material freeing an electron. ... Below, we briefly describe some of the common types of X-ray detectors that use these cascades of electrons to detect incoming X-rays.

All EM radiation travels at the speed of light. X- rays travel at same speed as microwaves.

Answer: An x-ray, like any photon, has zero mass; however it has kinetic energy, which is the energy that can do work. The energy is equal to Planck's constant (h) times the speed of light (c) divided by the x-ray's wavelength.

The difference between X-rays and visible light rays is the energy level of the individual photons. ... Our eyes are sensitive to the particular wavelength of visible light, but not to the shorter wavelength of higher energy X-ray waves or the longer wavelength of the lower energy radio waves.

The cathode is the electrode where reduction (gain of electrons) takes place (metal-B electrode); in a galvanic cell, it is the positive electrode, as ions get reduced by taking up electrons from the electrode and plate out (while in electrolysis, the cathode is the negative terminal and attracts positive ions from the ...

gamma rays are emitted by excited atomic nuclei. x-rays are emitted by excited electrons. gamma rays are smaller in wave length,higher in frequency,and carry on more energy than x-rays.

The x-rays project a picture onto film or send a digital image to a computer. ... Medical x-rays, dental x-rays, and mammograms use relatively low amounts of radiation. CT scans and fluoroscopic procedures result in higher radiation doses due to the need for multiple images and/or a longer exposure time.

X-ray imaging begins with a beam of high energy electrons crashing into a metal target and x-rays are produced. A filter near the x-ray source blocks these low energy rays, which means only the high energy rays pass through a patient toward a sheet of photographic film. X-ray can penetrate liquids, gas and solids.

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, and the beam passes through them.

X ray machine- ppt. ...  The x ray tube is made of Pyrex glass that encloses a vacuum containing two electrodes. Electrons are produced by the heated tungsten filament(cathode) and accelerated by a high potential difference to hit the target anode, where x rays are produced.

As they pass through the body, the energy from X-rays is absorbed at different rates by different parts of the body. A detector on the other side of the body picks up the X-rays after they've passed through and turns them into an image.

They consist of negatively charged material particles; electrons. They produce X rays. When a beam of cathode rays is made to fall upon a hard metallic target like Tungsten, X-rays are produced.

What Is an X-ray? This longstanding form of medical imaging is still one of the most useful. An X-ray is a procedure that produces images of the inside of your body. X-ray beams are a form of electromagnetic radiation, first discovered by German professor Wilhelm Conrad Roentgen in 1895.

All electromagnetic radiation, of which radio waves and X-rays are examples, travels at the speed c in a vacuum. The only difference between the two is that the frequency of X-rays is very much higher than radio waves.
