Question

Which of the following is not the application of X-ray
A. Diffraction
B. To analyse composing of material
C. Radio communication
D. Radiotherapy

Answer 1

First we know X-rays are a form of electromagnetic radiation similar to radio waves, microwaves, gamma rays and visible lights. This ray has a shorter wavelength of the electromagnetic spectrum and requires high voltage to produce X-Rays. They travel in a straight line and do not carry an electric charge with them. Also, they are capable of travelling in a vacuum. So used to transform information over short distances.

Complete answer:
(A) X-ray diffraction analysis (XRD) is a technique used in materials science to determine the crystallographic structure of a material. It works by irradiating a material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that leave the material.

(B) X-ray fluorescence (XRF) is an analytical technique used to determine the elemental composition of materials. It provides a very accurate method to measure the composition of materials and is used in the quality control of many industrial processes.

(C) Radio communication uses radio waves to transform information. Because radio waves have a longer wavelength than visible light and are used to carry information over long distances. Since the difference between a radio wave and an X-ray in a vacuum is that a radio wave has a much longer wavelength. X-rays have a much smaller wavelength and higher frequency compared to visible light. So, x-ray can’t be used in radio communication.

(D) Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells. Radiation therapy most often uses X-rays, but protons or other types of energy also can be used.

Hence, the correct answer is option C.

Note: X-rays are used to capture the human skeleton defects. X-ray diffraction also provides information on phases, preferred crystal orientations, and some structural parameters such as size, crystallinity, strain, and crystal defects. Radiography (or X-ray absorption) is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.
