Final answer:
The Bohr Model describes energy levels in an atom, while bright-line emissions refer to the specific wavelengths of light emitted by excited electrons.
Step-by-step explanation:
The Bohr Model is a simplified model of an atom that represents electrons in fixed energy levels or shells around the nucleus. These energy levels are quantized, meaning electrons can only occupy specific energy states. Bright-line emissions refer to the specific wavelengths of light emitted by excited electrons as they transition from higher to lower energy levels.
When an electron absorbs energy, it jumps to a higher energy level. As it returns to its original energy level, it releases the excess energy in the form of light. Each energy level corresponds to a specific energy difference, and these differences correspond to specific wavelengths of light. These wavelengths give rise to the bright spectral lines observed in emission spectra.
