18 Questions
What type of radiation is used in radiography to produce a shadow image of the internal structure of an object?
X-Rays
What is one characteristic of X-Rays used in radiography?
Adjustable energy level
Why do heavy and high atomic number metals appear opaque to radiation in radiography?
Related to their high density and atomic number
How does the absorption of high frequency radiation by materials relate to their appearance in a radiography image?
Materials with lower absorption appear darker in the image
What type of area within a material would be observed with greater blackening on a radiography image?
Area with lower atomic number and density
What is a key advantage of X-Rays used in radiography when compared to other types of electromagnetic radiation?
Adjustable energy level for penetration and contrast
What is the main purpose of using pulse-echo ultrasound in defect detection?
To determine the distance to defects by measuring the time for the waves to return
How are ultrasound waves transmitted through a material in defect detection?
Through transducers
What alteration can defects in a material cause in the echo pattern of ultrasound waves?
Decrease in amplitude of reflected waves
Which electronic instrument is used to generate and analyze ultrasound waves in defect detection?
Ultrasound detectors
How does pulse-echo ultrasound help in measuring elastic constants like Young's Modulus?
By measuring the time taken for waves to return from a defect
What is the relationship between the amplitude of reflected ultrasound waves and the size of defects in a material?
The larger the defect, the lower the amplitude of reflected waves
