Who invented x ray photographs?
German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays because he was the first to systematically study them.
Does ultraviolet light carry more energy than infrared radiation?
Yes. Radiations on the "red" end of the spectrum, such as radio, microwave, and infrared, have markedly less energy than visible light. Frequencies on the "purple" end, on the other hand, such as ultraviolet, x-ray, and gamma, have considerably more.
How did x-ray diffraction photographs help Watson and crick determine the structure of DNA?
It helped reveal the characteristic shape of a double helix
What has the longest wavelength-light waves x-rays or radio waves?
Radio Waves are in the lower end of the electromagnetic spectrum and have wavelengths between several hundred feet (AM Radio) to fractions of an inch (Microwave communications).
X-Rays are high energy photons at the upper end of the electromagnetic spectrum, with wavelengths shorter than visible light, measured in nanometers to picometers.
Color wise, Red is the longest visible, while Violet is the shortest wavelength of visible light.
There are many graphical charts of the electromagnetic spectrum that show where the various waves fit in relation to each other, these can be found on an internet image search.
Can airport x-ray machines damage camera film?
It depends on which kind. The small ones that you put your cary-ons through to get to the gate usually won't, but the big ones that you put your checked bags through probably will destroy your film. If you are concerned about your camera and film, ask for a manual search of the affected bags.
Which has the highest frequency gamma rays X-rays visible light radio waves?
Almost. They are shorter than radio waves, and they are the next order up from radio waves, but they have different properties in terms of interaction with materials. So right idea, wrong classification.

What is the similarities between X-rays and visible light?
Both beams seem to have wave/particle duality.
------------------------------------------
If we consider in a simple way the think, a focus electron beam behave somehow like a light beam even if it is a particle beam. Thus diffraction figures can be observed on a screen if the electron beam passes through a very small gap.
The great difference is that the equivalent wavelength of the electron beam seems to be very small with respect to light beam. The observed wavelength of an electron beam depends on electrons energy, being in general of the order of 1 nm (one meter part out of one billion) while green light has a wavelength of the order of 540 nm.
If we look more in deep the phenomenon, in quantum mechanics both a light beam and an electron beam are particle beams, being photons the light particles. They are in any case particle that do not resemble small rigid balls, but having quite exotic properties, like generating interference and, in case of photons, to be at light speed in any possible situation.
The basic difference is that electrons are fermions, with spin equal to 0.5 and a finite rest mass, while photons are bosons, with zero spin and zero rest mass. This difference causes the macroscopic difference in their behaviours.

you unlock the sky stair way by means of the spinda cafe .you talk to a Pokemon left from the entrance of the cafe and it will give you the mission given by scizor it can be any Pokemon and there are many missions obtained this way so try many times to find the one you want.you must have saved scizor from crevice cave first
How do the frequencies of infrared visible and ultraviolet light compare?
Visible light imagery only reveals what is reflected from the Earth's surface and atmosphere.
Infrared imagery detects the differences in thermal energy, which are used to map either cloud cover or surface temperatures. They allow meteorologists to determine the temperature of a cloud.
What they have in common:
Weather satellites used both of these equipment to observe the atmosphere.

Where are skull x rays performed?
Skull x rays are performed to examine the nose, sinuses, and facial bones. These studies may also be referred to as sinus x rays. X-ray studies produce films, also known as radiographs, by aiming x rays at soft bones and tissues of the body.
A dosimeter is an instrument that measures the amount of hazardous material to which something or someone has been cumulatively exposed. The most common is the radiation dosimeter, which measures a person's or object's exposure to radiation.
Answers
The X-ray was accidentally invented when Wilhelm Conrad Röntgen, a physics professor at Wurzburg, Bavaria, placed his hand in the path of the rays and saw an image of the bones of his hand on the screen.
An x-ray has a wavelength of 1.3A calculate the energy in J of one photon of this radiation?
To calculate the energy of one photon, you can use the formula E = hc/λ, where h is Planck's constant (6.63 x 10^-34 J s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength in meters. Plugging in the values, the energy of one photon with a wavelength of 1.3 Å (1.3 x 10^-10 m) is approximately 9.59 x 10^-16 J.
What are the differences between X-rays and alpha rays?
X-rays are electromagnetic waves with high energy and penetrate through tissues, used in medical imaging. Alpha rays are particles emitted by radioactive materials, consisting of two protons and two neutrons, and have low penetration power but high ionization ability. In terms of health effects, exposure to X-rays can increase the risk of cancer, while exposure to alpha rays can cause significant damage if internalized.
The frequency of the ray can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values, we get frequency = 2.998 x 10^8 / 3.10 x 10^14 = 9.67 x 10^5 Hz.
Difference between rotating anode x ray tube and stationary x ray tube?
A rotating anode promotes cooling between exposures by distributing the intense beam from the cathode over the surface of the anode. A rotating anode tube lasts a lot longer than a stationary x-ray tube.
How do X-Rays reveal the structure of atoms within crystals?
When we set up a crystal target and X-ray it, the crystal scatters the X-rays. By examination and noting the angles at which the scattering occurs, and also the varying intensities of the scattered radiation, investigators can figure out the structure of the atoms within that crystal structure. This is called X-ray crystallography, and it relies on what we call X-ray diffraction. The technology has been around for quite a while, having been developed in the early part of the 20th century.
What materials would stop X rays from passing through them?
Materials like lead, concrete, steel, and barium are effective in stopping X-rays from passing through them due to their high density and atomic number. Lead is commonly used in protective garments worn by medical personnel during X-ray procedures.
What are parts of Rotating anode dual focus x-ray tube?
A cathode ray tube will emit electrons boiled off a heater located in the cathode area. As electrons leave the cathode traveling to a more positive potential located at the plate a grid of negative potential can deflect, impede these electrons flow.
1. Medical Uses:
i. Radiography : Radiography is an imaging technique that uses electromagnetic radiation other than visible light, to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density and composition) such as the human body.
ii. Computed Tomography: Computed Tomography (CT scanning) is a medical imaging modality where tomographic images or slices of specific areas of the body are obtained from a large series of two-dimensional X-ray images taken in different directions.
iii. Fluroscopy: Fluroscopy is an imaging technique commonly used by physician or radiation therapist to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope.
iv. Radiotherapy: The use of X-rays as a treatment is known as radiation therapy and is largely used for the management of cancer; it requires higher radiation energies than for imaging alone.
2. X-ray crystallography in which the pattern produced by the diffraction of X-rays through the closely spaced lattice of atoms in a crystal is recorded and then analysed to reveal the nature of that lattice. A related technique, fiber diffraction, was used by Rosalind Franklin to discover the double helical structure ofDNA.

4. X-ray microscopic analysis, which uses electromagnetic radiation in the soft X-ray band to produce images of very small objects.
5. Industrial radiography uses X-rays for inspection of industrial parts, particularly welds.
Components of rotating anode x ray tube?
rotating anode
1)During a operation large shaped disc tungsten anode rotate at speed 3000 t0 9000rpm(resolution per minute).
2)A motive force to rotate the anode is given by induction motor.therefore windings of which is housed outside the tube.
3)a design element help to limit power density delivered on the physical focal spot while making a small effective focal spot.
4)with rotating anode,heat is produced during exposure is spread over the large area of anode.thereby increases the heating loading capacity of the tube and allowing high power level are used as a result which produces the x radiation.
5) by increasing the anode voltage x rays which produces the shortest wavelength this is used to therpeutic.
by decresing the anode current which produces the longest wavelength this is used for diagnostic process.
What wave has a higher frequency microwave of X-ray?
An X-ray is a high frequency (high energy) electromagnetic wave. It is much higher in frequency than any broadcast wave. The only electromagnetic radiation with higher frequency (shorter wavelength) than the X-ray is the gamma ray.
