X-Ray

Mostly neutron stars are detected with radio telescopes. Some can actually be seen with optical telescopes, and these are all optical pulsars.

Neutron stars were discovered because they are radio sources. The first star known to be a neutron star was the Crab Nebula neutron star, or Crab Pulsar, which was discovered to be a neutron star because of its radio emissions in 1965. Its apparent magnitude is 16.5. This puts it beyond the abilities of most amateur telescopes.

X-rays and gamma rays are both forms of electromagnetic radiation, but differ in their origins. X-rays are typically produced by accelerated electrons hitting a target, while gamma rays originate from nuclear processes like radioactive decay or nuclear reactions. Gamma rays have higher energy and penetrating power compared to X-rays, making them more harmful to living organisms.

X-ray photographs taken by Rosalind Franklin provided key information about the structure of DNA, suggesting a helical shape with a repeating pattern. Watson and Crick used this data to build a model of the DNA molecule, leading to their discovery of the double helix structure. Franklin's work was crucial in providing the evidence necessary for Watson and Crick to propose their groundbreaking model.

The Chandra X-ray Observatory operates in space because Earth's atmosphere absorbs X-rays, preventing them from reaching ground-based telescopes. By locating the observatory in space, it can capture X-rays from distant celestial objects without interference, providing clearer and more detailed images of the universe. Additionally, operating in space allows Chandra to observe continuously without the interruptions caused by Earth's day-night cycle.

To extract silver from old X-ray films, the films need to be shredded into small pieces. These pieces are then treated with chemicals to dissolve the emulsion layer containing the silver halide. The silver can then be extracted from the solution using a process such as electrolysis or chemical precipitation.

The range of wavelengths for X-rays is typically between 0.01 to 10 nanometers. X-rays have shorter wavelengths and higher energy compared to visible light, making them suitable for medical imaging, security screening, and materials analysis.

The simple answer is 'they do.'

If you were to hold a piece of paper up to direct sunlight, you would be able to the sunlight coming through the paper. The paper is opaque but not completely so, some light does get through. If you were to put a piece of glass on top of this piece of paper you would see it too. Even though glass is transparent to visible light it still has refractive and reflective properties that effect the light that falls on it.

The same is true for x-rays. Flesh and bone is opaque to x-rays but not completely so. Shining x-rays on a limb will show something of the things in it.

X-rays have higher energy and shorter wavelengths than visible light rays, allowing them to penetrate deeper into materials and tissues. This property makes X-rays useful for imaging bones and other dense structures in the body. Additionally, the production of X-rays involves high-voltage electricity and specialized equipment, contributing to their higher power compared to visible light rays.

NASA named its X-ray telescope after Indian astrophysicist Subrahmanyan Chandrasekhar, in recognition of his groundbreaking work on the evolution and structure of stars. The Chandra X-ray Observatory was launched in 1999 and continues to provide valuable insights into the high-energy universe.

Cosmic rays are not part of the electromagnetic spectrum. They are high-energy particles, such as protons and atomic nuclei, that travel through space at nearly the speed of light. Unlike electromagnetic waves, which are composed of oscillating electric and magnetic fields, cosmic rays are actual particles with mass.

The shape is a helical structure known as the double helix, which is the twisted ladder-like form of DNA. Rosalind Franklin's x-ray diffraction images provided crucial evidence for the structure, and Watson and Crick built a model to accurately represent the DNA molecule's double helix shape.

X rays are of a much higher energy than visible light, so they have more penetrating power. So they can easily penetrate tissue, but they penetrate bones less well, and most metals almost not at all.

Yes, X-rays can see through wood. Wood is not dense enough to completely block X-rays, allowing them to pass through and produce an image on the other side. This property makes X-rays useful for inspecting wooden objects for defects or hidden features.

X-rays are a kind of electromagnetic radiation - similar to light. They travel at the speed of light through a vacuum - about 300 million meters/second.

Because soft x-rays are not as penetrative as hard x-rays they are considered more dangerous as not all the radiation passes straight through the body. Radiation is considered harmful to newly dividing cells. Examples of soft x-rays are dental x-rays and mammograms.

We see color in the electromagnetic spectrum because different wavelengths of light correspond to different colors. Our eyes have specialized cells called cones that are sensitive to different wavelengths of light. When light enters our eyes, the cones are activated, sending signals to our brain that allow us to see and interpret colors. Ultraviolet, infrared, X-rays, and gamma rays are outside the visible spectrum, so we cannot see them as colors, but rather, we use specialized sensors or equipment to detect and interpret them.

A device used for removing long wavelength radiation from the primary x-ray beam is called a filter. Filters are designed to absorb or attenuate low-energy photons, thus improving image quality and reducing patient dose during radiographic procedures.

The four essential elements required for x-ray production are a source of electrons (cathode), a target material (anode), a high voltage to accelerate the electrons towards the target, and an appropriate vacuum in the x-ray tube to allow electrons to travel from cathode to anode without obstruction.

Marie Curie did not invent the X-ray machine; this was Mr. Rontgen who figured out how to produce radiographs.

Ms. Curie was one of the pioneers who first identified and described radiation; this is why radiation levels are often measured in curies - the unit was named in her honor.

X-rays are electromagnetic waves - that is, of the same nature as visible light. However, their frequency and therefore their energy are much higher than that of visible light, while their wavelength is much lower.

An X Ray has the wavelength of precisely 1000 nm or nanometers. X Rays can penetrate the human skin without as much damage to cells that gamma rays do.

The wavelength of a gamma ray is 10^-12m, or 0.0000000000000001 m, or 0.0001 nm.

Gamma rays are capable of damaging human skin, as well as being used to locate organisms in a certain environment. In 1896, a pulse of gamma rays was released from a nuclear powerplant in Sevsky, Australia. As the waves traveled, they became weaker. Everything within a 3.86 mile radius of the pulse became ill, and had to take FrCg5 pills (Frocedien Cargocide [V]) for the rest of lives in order to stay alive from Radiation Posioning.

I hope you use this information wisely.

Draping the trunk of your body during an x-ray procedure helps to protect sensitive reproductive organs from unnecessary radiation exposure. This extra layer of protection reduces the risk of potential harm to these organs.

Yes, astronomers use ground-based X-ray telescopes to study high-energy phenomena in space. These telescopes are typically located at high-altitude sites to reduce interference from Earth's atmosphere and are used to observe sources such as black holes, neutron stars, and supernova remnants.
