  1. Question 1

    Q1. Electron transitions between energy levels in a mercury atom produce light. Which emission spectrum line corresponds to the highest energy transition? Assume all options are within the visible spectrum.

    • A) Blue line (435 nm)
    • B) Green line (546 nm)
    • C) Red line (610 nm)
    • D) Yellow line (577 nm)

    Answer: Blue line (435 nm)

    Explanation: Blue light (435 nm) has the shortest wavelength and highest energy. Longer wavelength options (B/C/D) correspond to lower energy transitions.
