  • 2. 

    X-Rays can be generated from atoms and free electrons.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    X-rays can be generated from atoms and free electrons. This is true because X-rays are produced when high-energy electrons collide with atoms, causing the electrons in the atoms to be excited and then release energy in the form of X-rays. Additionally, X-rays can also be generated through the process of Bremsstrahlung, where fast-moving electrons are decelerated by a target material, resulting in the emission of X-rays. Therefore, both atoms and free electrons can contribute to the generation of X-rays.

    Why silhouettes of bones and teeth are left on the X-ray film?

    • They are less dense and absorb less x-rays

    • They are more dense and absorb more x-rays

    Correct Answer
    A. They are more dense and absorb more x-rays
    Explanation
    The silhouettes of bones and teeth are left on the X-ray film because they are more dense and absorb more x-rays. X-rays are a form of electromagnetic radiation that can pass through soft tissues, such as muscles and organs, but are absorbed by denser materials like bones and teeth. This differential absorption creates the contrast on the X-ray film, allowing the visualization of these structures.

    X-Rays were first observed and documented by?

    • Wilhelm Conrad Roentgen

    • Tom Conrad Roentgen

    • Wilfred Conrad Roentgen

    Correct Answer
    A. Wilhelm Conrad Roentgen
    Explanation
    Wilhelm Conrad Roentgen is credited with being the first person to observe and document X-rays. He made this discovery in 1895 while experimenting with cathode rays. Roentgen's groundbreaking work led to the development of X-ray technology, which has since revolutionized medical imaging and diagnostics. His discovery earned him the first Nobel Prize in Physics in 1901.

    X-rays have a longer wavelength than visible light

    • True

    • False

    Correct Answer
    A. False
    Explanation
    X-rays have a shorter wavelength than visible light. X-rays are a form of electromagnetic radiation with very high energy and short wavelengths, while visible light has longer wavelengths. This is why X-rays can pass through certain objects and are used in medical imaging, while visible light is used for everyday vision.
