MDCAT Chemistry MCQ #749

  1. Question 1

    Q1. The frequency of a spectral line is related to the energy difference between two levels by

    • A) ΔE = hν
    • B) λ = h/p
    • C) E = mc²
    • D) ν = c/λ

    Answer: ΔE = hν

    Explanation: ΔE = hν relates energy difference to frequency; λ = h/p is de Broglie's equation for particle wavelength.
