Why does the colour of an iron nail and copper sulphate solution changes its colour when dipped ? |
Answer» AnswEr :-The key to the explanation is the single displacement reaction. As we know that iron is more REACTIVE than copper, the more reactive metal displaces the less reactive metal. This is the reason why the copper sulphate solution colour CHANGES its colour from blue to pale green. Also, the iron NAIL becomes brownish in colour. Reaction :- |

Both cathode and anode rays rotate a light paddle kept between the anode and cathode. What do you conclude from this about anode and cathode rays?(plz answer this question as soon as possible) |
|
Answer» Explanation: The ELECTRODE of a battery that releases electrons during DISCHARGE is called anode; the electrode that absorbs the electrons is the cathode. The battery anode is always negative and the cathode positive. This appears to violate the convention as the anode is the TERMINAL into which current flows JJ Thomson did an experiment with discharge tube USING hydrogen gas. Later it was found that anode RAYS and Cathode rays both exist at the same time.. ... |

Answer» In the physical SCIENCES, the wavenumber (also wave number or repetency) is the spatial frequency of a wave, measured in CYCLES per unit distance or radians per unit distance. Whereas temporal frequency can be thought of as the number of waves per unit time, wavenumber is the number of waves per unit distance. In multidimensional systems, the wavenumber is the magnitude of the wave vector. The space of wave vectors is CALLED reciprocal space. Wave numbers and wave vectors PLAY an essential role in optics and the physics of wave scattering, such as X-ray diffraction, neutron diffraction, ELECTRON diffraction, and elementary particle physics. For quantum mechanical waves, the wavenumber multiplied by the reduced Planck's constant is the canonical momentum. Wavenumber can be used to specify quantities other than spatial frequency. In optical spectroscopy, it is often used as a unit of temporal frequency assuming a certain speed of light. |
