The History of the X-Rays

- ... (2.) A man named William David Coolidge solved this debacle by creating the vacuum sealed Coolidge Tube, which not only allowed an increase in power through the tube that allowed better pictures, but it also permitted more stability in the x-ray tubes, thus giving them a longer working lifespan. The Coolidge tube could operate to energies up to 100,000 volts. General Electric went on to make x-ray tubes capable of operating at energies up to 1,000,000 volts, which gave the x-ray technology enough stability to become industrialized and mass produced....   [tags: crystals, rays, medicial, industial]

The Use of X-rays for Diagnosis and Therapy

- According to Oxford Dictionaries, an X-ray, also known as a type of radiation is defined as an electromagnetic wave of high energy and very short wavelength (between ultraviolet light and gamma rays), which is able to pass through many materials opaque to light and being absorbed to different degrees by different materials. In medicine, an X-ray is produced by the deceleration of charged particles, especially electrons, or by electron transitions in atoms. An X-ray machine sends these particles through the body....   [tags: Use of X-rays]

How to Measure Energy Cosmic Rays

- Cosmic rays are to scientists much like photons are to astronomers. Just as astronomers use light (or photons) to view our galaxy and beyond, scientists use cosmic rays to infer useful properties about our galaxy. In fact, cosmic rays offer one of the few ways in which scientists can actually sample real matter outside of our solar system. By identifying the various nuclei that are dispersed throughout our Galaxy, scientists hope to unravel the mechanisms that actually produce these nuclei -- from stellar nucleosynthesis to nucleosynthesis within supernovae to nuclear fragmentation....   [tags: cosmic rays, galaxy, nuclear fregmentation]

The Discovery of X-Rays

- From the ancient time probably one of the most popular questions among people was how their bones re constructed, and how they are joned. Moreover, it was alsmost impossible for surgeons to identify where in the body bullets can be located and consequently a successful removement of it was equalized to magic. This situation continued until late 1895, when a German physicist, Wilhelm Conrad Roentgen, discovered X-rays, and as a result he invented a mechanism of filming human bones in a picture ( Tice 2007, 1)....   [tags: Benefits, History]

Why the Moon Appears to Change Color

- The reason the moon appears to change color is due to the reflection of visible light coming from the sun. Because the moon has no light of its own it relies on the reflected light of the sun to create moonlight and change color. The reflection of light coming from the sun cause’s the moon to appear as if it is changing color because as the sun’s light rays travel through the earth’s atmosphere the moon catches light from the sun and reflects it down to earth. As the moon reflects the sun’s light rays down to earth, those rays of light travel through the earth’s atmosphere in the form of different wavelengths which then produce different colors of visible light....   [tags: visible light, reflection, color, rays]

Well my friend, look no further... the answers to your 2 most burning questions are about to come. First of all, what happens when we see images. Our eye acts as a simple model of a lens system. The average adult eye is about 25 mm in diameter. As light enters our eye, it is refracted first through the cornea which does about 80% of the refracting. The crystalline lens which is located after the aqueous humour (just under the cornea) approximately contributes the rest....   [tags: Math Vision]

The Aftermath of UV Exposure

- As summer fast approaches, everyone begins to make their plans for some fun at the beach. This is time for one to get a nice tan from the UV rays of the sun. Some might get a tan at a tanning salon even before they hit the waves. But is the aftermath really worth the tan. Is there even any way to get a safe tan. The effects of the UV light have both positive and negative consequences on the body. Vitamin D intake and phototherapy are both positive factors. Negatively, UV light can lead to skin cancer and eye damage....   [tags: vitamin d, tanning salon, beaches]
