X-rays can be used to:
1. inspect welded joints between two metal parts of a machine.
2. study structure of crystals.
Select the answer using the code given below:

Correct option is C

The correct answer is (c) Both 1 and 2. X-rays have multiple applications due to their ability to penetrate various materials.
Inspect welded joints between two metal parts of a machine: X-rays are commonly used in non-destructive testing (NDT) to inspect welded joints and detect internal defects or discontinuities within metals. This method is widely used in industries such as construction and manufacturing to ensure the integrity of structures and machinery.
Study structure of crystals: X-rays are also used in X-ray crystallography, a technique that helps determine the atomic and molecular structure of crystals. When X-rays are directed at a crystal, they are diffracted, producing a pattern that can be analyzed to reveal the crystal's internal lattice structure. This application is crucial in chemistry, physics, and biology for studying the arrangement of atoms in substances.
Information Booster: ● X-ray inspection is vital in quality control, especially in welding, as it reveals defects like cracks, voids, and porosity within the joints. ● X-ray crystallography has been instrumental in discovering the structure of DNA, proteins, and many other compounds. ● The ability of X-rays to penetrate and create images makes them useful not only in medicine (X-ray imaging) but also in industrial applications. ● The wavelengths of X-rays are small enough to interact with the atomic structure of materials, making them ideal for studying crystal formations. ● Other uses of X-rays include airport security, where they screen luggage for prohibited items. ● X-rays are a powerful tool in scientific research, aiding in the analysis of materials and biomolecular structures.
