~ nats 1580 sun, space weather and life on earth ~ Doppler effect: is the change in frequency or wavelength of a wave in relation to observer who is moving relative to the wave source google. ca. When one speaks, his/her voice vibrates back and forth, allowing one to hear what the other is saying. Solar surface motions are due to sound waves from the interior of the sun. Blue and red shift: motion towards us makes the light bluer, motion going away from is redder. According to the bohr atomic model, electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an energy level: electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels. Each atom"s or molecules spectrum is unique; its like a fingerprint.
