J.J. Thomson Quiz


Questions and Answers
  • 1. 
    What was it that J.J. Thomson discovered?
    • A. 

      The Atom

    • B. 

      Corpuscles

    • C. 

      Sub-Atomic Particles

  • 2. 
    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

  • 3. 
    When was the corpuscle discovered by Thomson?
    • A. 

      One hundred years ago

    • B. 

      Two hundred years ago

    • C. 

      Fifty 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.

  • 5. 
    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.

  • 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

  • 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.

  • 8. 
    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.
