The first three energy levels of the fictitious element X are shown in (Figure 1). Part A What wavelengths are observed in the absorption spectrum of element X? Express your answers in nanometers. Enter your answers in descending order separated by commas. A360,280 nm Submit Previous Answers Part B Correct State whether each of your wavelengths in the previous parts corresponds to ultraviolet, visible, or infrared light. Check all that apply. visible light ultraviolet light infrared light Submit Previous Answers Part C Correct An electron with a speed of 1.8 × 106 m/s collides with an atom of element X. Shortly afterward, the atom emits a 1240 nm photon. What was the electron's speed after the collision? Assume that, because the atom is so much more massive than the electron, the recoil of the atom is negligible. Hint: The energy of the photon is not the energy transferred to the atom in the collision. Express your answer with the appropriate units. ΜΑ m v -1.143.10 S ?
