  1. Question 1

    Q1. During a discharge tube experiment, high-velocity cathode rays strike the glass walls of the tube. What is the observable result of this specific interaction?

    • A) Produce X-rays immediately
    • B) Produce a greenish fluorescence
    • C) Cause the glass to melt
    • D) Reflect back to the cathode

    Answer: Produce a greenish fluorescence

    Explanation: Cathode rays produce fluorescence when striking glass; X-rays are only produced when these rays hit heavy metal targets like tungsten.
