  2. Bicycle lighting - Wikipedia

    en.wikipedia.org/wiki/Bicycle_lighting

    Red light on the back of a bicycle Early bicycle lighting: candle lamps, oil lamps and carbide lamps Early bicycle lamps and two early bottle dynamos (1935). Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination.

  3. Emission spectrum - Wikipedia

    en.wikipedia.org/wiki/Emission_spectrum

    The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted. Emission spectrum of hydrogen. The above picture shows the visible light emission spectrum for hydrogen. If ...

  4. Hydrogen spectral series - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_spectral_series

    The Bohr model was later replaced by quantum mechanics in which the electron occupies an atomic orbital rather than an orbit, but the allowed energy levels of the hydrogen atom remained the same as in the earlier theory. Spectral emission occurs when an electron transitions, or jumps, from a higher energy state to a lower energy state.

  5. Proton pack - Wikipedia

    en.wikipedia.org/wiki/Proton_pack

    A replica of the ghost trap used in the original film. The proton pack, designed and built by Dr. Egon Spengler, is a man-portable cyclotron system (and indeed Dr. Peter Venkman refers to the proton packs in one scene as "unlicensed nuclear accelerators"), [3] that is used to create a charged particle beam—composed of protons—that is fired by the particle thrower (also referred to as the ...

    Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.

  7. Lyman series - Wikipedia

    en.wikipedia.org/wiki/Lyman_series

    In physics and chemistry, the Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number), the lowest energy level of the electron (groundstate).
