Why do the sun's rays feel hotter in the afternoon than in the morning or evening?
because intensity of rays is more in afternoon
What type of college that you have to attend to become an x ray technician?
The following is written by and according to the U.S. Department of Labor and particular to the education and training required for an X-Ray Technician.
Preparation for this profession is offered in hospitals, colleges and universities, and less frequently at vocational-technical institutes. Hospitals employ most radiologic technologists. Employers prefer to hire technologists with formal training.
Education and training. Formal training programs in radiography range in length from 1 to 4 years and lead to a certificate, an associate degree, or a bachelor's degree. Two-year associate degree programs are most prevalent.
Some 1-year certificate programs are available for experienced radiographers or individuals from other health occupations, such as medical technologists and registered nurses, who want to change fields. A bachelor's or master's degree in one of the radiologic technologies is desirable for supervisory, administrative, or teaching positions.
The Joint Review Committee on Education in Radiologic Technology accredits most formal training programs for the field. The committee accredited more than 600 radiography programs in 2007. Admission to radiography programs require, at a minimum, a high school diploma or the equivalent. High school courses in mathematics, physics, chemistry, and biology are helpful. The programs provide both classroom and clinical instruction in anatomy and physiology, patient care procedures, radiation physics, radiation protection, principles of imaging, medical terminology, positioning of patients, medical ethics, radiobiology, and pathology.
Licensure. Federal legislation protects the public from the hazards of unnecessary exposure to medical and dental radiation by ensuring that operators of radiologic equipment are properly trained. Under this legislation, the Federal Government sets voluntary standards that the States may use for accrediting training programs and licensing individuals who engage in medical or dental radiography. In 2007, 40 states required licensure for practicing radiologic technologists and technicians.
Certification and other qualifications. The American Registry of Radiologic Technologists (ARRT) offers voluntary certification for radiologic technologists. In addition, 35 States use ARRT-administered exams for State licensing purposes. To be eligible for certification, technologists generally must graduate from an accredited program and pass an examination. Many employers prefer to hire certified radiographers. To be recertified, radiographers must complete 24 hours of continuing education every 2 years.
Radiologic technologists should be sensitive to patients' physical and psychological needs. They must pay attention to detail, follow instructions, and work as part of a team. In addition, operating complicated equipment requires mechanical ability and manual dexterity.
Advancement. With experience and additional training, staff technologists may become specialists, performing CT scanning, MR, and angiography, a procedure during which blood vessels are x rayed to find clots. Technologists also may advance, with additional education and certification, to become a radiologist assistant.
Experienced technologists also may be promoted to supervisor, chief radiologic technologist, and, ultimately, department administrator or director. Depending on the institution, courses or a master's degree in business or health administration may be necessary for the director's position.
Some technologists progress by specializing in the occupation to become instructors or directors in radiologic technology programs; others take jobs as sales representatives or instructors with equipment manufacturers.

What is the principle behind x-ray technique?
As with many of mankind's monumental discoveries, '''X-ray technology was invented completely by accident. In 1895, a German physicist named Wilhelm Roentgen made the discovery while experimenting with '''electron beams in a '''gas discharge tube. Roentgen noticed that a flouorescent screen in his lab started to glow when the electron beam was turned on. This response in itself wasn't so surprising -- fluorescent material normally glows in reaction to electromagnetic radiation -- but Roentgen's tube was surrounded by heavy black cardboard. Roentgen assumed this would have blocked most of the radiation.
Roentgen placed various objects between the tube and the screen, and the screen still glowed. Finally, he put his hand in front of the tube, and saw the silhouette of his bones projected onto the fluorescent screen. Immediately after discovering X-rays themselves, he had discovered their most beneficial application. '''''''''
Roentgen's remarkable discovery precipitated one of the most important medical advancements in human history. X-ray technology lets doctors see straight through human tissue to examine broken bones, cavities and swallowed objects with extraordinary ease. Modified X-ray procedures can be used to examine softer tissue such as the lungs, blood vessels or the intestines.

They definitely do exist.
X-rays are a type of electromagnetic radiation (like visible light, radio waves, microwaves, etc) with a wavelength of 10 - 0.01 nanometers, or about 100 times shorter than visible light on average. X-rays can be generated by machines used in medicine, and are also part of background radiation in the cosmos. Over exposure can be very dangerous; many governments set limits on the amount of x-rays that an individual can safety be exposed to in a given time period.

Do you say an X-ray or do you say a X-ray?
an X-ray
similarly to the way you would say "an hour" even though the first letter is a consonant

Xray speed in a vacum is equal to the spped of visible light, 186,000 miles per second, or 300,000 km per second. Outside of a vacum, x-ray waves are subject to various factors that change speed.
In order of increasing energies: # radio waves, passes through ozone. # microwaves, passes through ozone, but there are some resonances in "spinning" the molecule at a few tens of frequencies. # infrared, ozone absorbs some infrared... it is a molecule with more than two atoms. # visible light, very little interaction with all but blue. # ultraviolet light, UV-A passes through, UV-B and UV-C are absorbed. # X-rays, absorbed. # gamma rays, absorbed. Now it is important how much ozone is available along any given path for absorbing the radiation. Gases are very sparse, so "completely absorbed" doesn't happen. In addition, UV-C and more energetic are absorbed by all gases in our atmosphere. Ozone is unique in absorbing UV-B, and shares absorbing infrared with things like methane and water vapor.
