This set of Engineering Physics Multiple Choice Questions & Answers (MCQs) focuses on “Applications of X-Rays”.
1. Photographs made with X rays are known as ___________
d) Scanned Photos
Explanation: Radiographs are the photographs that are made with the help of X-ray. It is widely used in the medical field. It can be used for diagnosis and non-destructive testing of products to identify defects in it.
2. X-rays are used with computer in __________
a) CT Scan
b) CAT Scan
c) CA Scan
d) AT Scan
Explanation: X-rays are used with computers for CAT Scan. They are used to produce cross-sectional images of the inside of the body.
3. Radiography can be used to identify the age of a painting.
Explanation: Radiography can be used to identify the age of the painting or the brushing technique used in the painting. It can be used to verify the artist of the painting.
4. Which of the following disease can be detected by X-Ray?
a) Bladder infection
Explanation: After taking a chest x-ray test, pneumonia can be diagnosed. If there are white spots on the lungs, it means that the person has pneumonia.
5. The therapy used to fight cancer cells is called __________
a) Cancer therapy
b) X-ray therapy
d) Diagnosis therapy
Explanation: When x-ray radiations are used to destroy the cancer cells, it is called as radiation therapy or brachytherapy. It can be dangerous.
6. The checking of bags in Airport is done via X-ray.
Explanation: Since, X-ray has high penetrating power, it is widely used in airport security to check the items/belongings of a person. Full body x-ray scans are also widely used.
7. The food industry uses X-ray for __________
a) Checking Purity of food
b) Sterilizing food
c) Break it into smaller pieces
d) Does not uses
Explanation: X-ray and Gamma rays both are used in food industries for sterilizing the food. It is a good health safety measure and has minimum side effects.
8. In photo-chemical process, the rays which provide better resolution are __________
b) Visible Light
c) UV light
Explanation: Since X-ray have much shorter wavelength comparing to the visible light, they are considered a promising option to provide better resolution in photo-chemical processes such as semiconductor etching etc.
9. The process of using X-rays for identifying atomic structure is called _________
a) X-ray Radiography
b) X-ray Crystallography
c) X-ray Diagnosis
d) X-ray Structure Identification
Explanation: X-ray crystallography is used to identify the molecular and atomic structure of the crystal. The crystal diffracts the incident X-ray beam. By measuring the intensities and angle of these diffracted beams, the molecular structure of the crystal can be evaluated.
Explanation: The given figure shows the procedure of X-ray scan. X-ray scan can be used to identify any fracture in bones, tumor, cancerous tissues and many more diseases.
