the bohr model of the atom explained why emission spectra are discrete. it could also be used to explain the photoelectric effect. which is a correct explanation of the photoelectric effect according to the model?\nelectrons are emitted with more speed when brighter light strikes them.\nelectrons need small amounts of energy to be released from an atom.\nelectrons move between levels only if they are hit by the right frequency of light.\nelectrons need specific amounts of energy to jump levels and be emitted.
Answer
Brief Explanations:
The Bohr model posits that electrons occupy discrete energy levels. For an electron to jump to a higher - energy level and be emitted (in the context of the photoelectric effect), it needs a specific amount of energy corresponding to the energy difference between levels. Brighter light just means more photons but not necessarily more energy per photon to affect electron emission speed in the way described in the first option. Small amounts of energy may not be sufficient to release electrons as they need to reach specific energy thresholds. And it's not just about the right frequency for moving between levels and being emitted, but the specific energy associated with that frequency to make the electron jump levels and be ejected.
Answer:
Electrons need specific amounts of energy to jump levels and be emitted.
