    What was the cathode ray tube?

    • A.

      A Glowing Glass Tube

    • B.

      A high vacuum tube in which cathode rays produce a luminous light

    • C.

      A beam of electrons emitted from a cathode

    Correct Answer
    B. A high vacuum tube in which cathode rays produce a luminous light
    Explanation
    The cathode ray tube was a high vacuum tube in which cathode rays produced a luminous light. This means that when a high voltage was applied to the cathode, electrons were emitted and accelerated towards the anode, creating a beam of electrons. This beam of electrons then struck a phosphorescent screen, causing it to emit a glowing light. This technology was widely used in early television sets and computer monitors.

    When was the corpuscle discovered by Thomson?

    • A.

      One hundred years ago

    • B.

      Two hundred years ago

    • C.

      Fifty years ago

    Correct Answer
    A. One hundred years ago
    Explanation
    Thomson discovered the corpuscle one hundred years ago.

  • 4. 

    How did J.J. know he discovered something smaller than the atom?

    • A.

      Atoms have neutral charges and these particles rushed from the negative to the positive terminals creating a ray of light.

    • B.

      He found the mass charge ratio and the particles rushed to the positive terminal and atoms have a positive charge.

    Correct Answer
    A. Atoms have neutral charges and these particles rushed from the negative to the positive terminals creating a ray of light.
    Explanation
    J.J. knew he discovered something smaller than the atom because he observed that the particles rushed from the negative to the positive terminals, creating a ray of light. This suggests that the particles had a charge and were being attracted to the positive terminal. Since atoms have neutral charges, the presence of charged particles indicates the existence of something smaller than an atom.

    How does the cathode ray tube work?

    • A.

      The particles which are the electrons originate at the heated cathode, negative part of the tube, and then will rush to the anode which is the positive side of the tube. The stream the electrons create is what lights up the tube.

    • B.

      The particles which are the electrons originate at the heated anode, positive part of the tube, and then will rush to the cathode which is the negative side of the tube. The stream the electrons create is what lights up the tube.

    • C.

      A tube that contains cathode rays shooting through it. This creates the beam of light.

    Correct Answer
    A. The particles which are the electrons originate at the heated cathode, negative part of the tube, and then will rush to the anode which is the positive side of the tube. The stream the electrons create is what lights up the tube.
    Explanation
    The correct answer explains that the electrons originate from the heated cathode, which is the negative part of the tube, and then rush towards the anode, which is the positive side of the tube. The stream of electrons creates the light in the tube.

  • 6. 

    The corpuscle, now known as the electron, was discovered one hundred years ago by British Physicist, J.J. Thomson 100 years ago at the Cavendish Laboratory at Cambridge University. 

    • A.

      False

    • B.

      True

    Correct Answer
    B. True
    Explanation
    The explanation for the given correct answer, which is "True," is that the corpuscle, which is now known as the electron, was indeed discovered by British Physicist J.J. Thomson 100 years ago at the Cavendish Laboratory at Cambridge University. This discovery was a significant milestone in the understanding of atomic structure and led to the development of modern atomic theory.

    Rate this question:

  • 7. 

    The corpuscle was discovered using cathode rays.

    • A.

      True, the corpuscle was discovered using cathode rays.

    • B.

      False, the corpuscle was discovered using cathode ray tubes.

    Correct Answer
    B. False, the corpuscle was discovered using cathode ray tubes.
    Explanation
    The statement in the answer is false. The corpuscle was not discovered using cathode ray tubes. Instead, it was discovered using cathode rays.

    What was Thomson's bold proposal?

    • A.

      The mysterious rays are streams of particles much smaller than atoms, small pieces of atoms.

    • B.

      The mysterious rays are streams of atoms, grouped together, and negatively charged.

    Correct Answer
    A. The mysterious rays are streams of particles much smaller than atoms, small pieces of atoms.
    Explanation
    Thomson's bold proposal was that the mysterious rays are not streams of atoms, but rather streams of particles that are much smaller than atoms. He believed that these particles were small pieces of atoms, which challenged the prevailing belief at the time that atoms were indivisible. This proposal revolutionized the understanding of atomic structure and laid the foundation for the discovery of subatomic particles such as electrons.
