Who said light is a particle? Einstein Who discovered the particle nature of light? The mathematical theory of electromagnetism by James Clerk Maxwell, set up in 1864, led to the view that light is of electromagnetic nature, propagating as a wave from the source to the receiver. Heinrich Hertz discovered experimentally the existence of electromagnetic […]

What happens if atmospheric pressure is too high?
What happens if atmospheric pressure is too high? As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die. What is considered high pressure weather? A barometer reading of 30 inches (Hg) is […]
What proves a permanent magnet?
What proves a permanent magnet? A high magnetic ordering temperature (called the “Curie temperature” or Tc), below which the material is spontaneously magnetic. A large remanent magnetic flux (called “remanence” or Br) maintained in the absence of an external magnetic field. A strong resistance to demagnetization (called “coercivity” or Hc) What is the strength of […]

What results when two atoms share electrons?
What results when two atoms share electrons? A covalent bond results when two atoms share electrons. In the case of two hydrogen atoms, each shares its single electron with the other. This sharing allows each to fill its electron shell with two electrons. The pair of shared electrons constitutes a covalent single bond. How many […]
What is say is a path of electricity one word answer?
What is say is a path of electricity one word answer? An electric circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. Is a closed path that allows electricity to flow from one point to […]
What are three sources of geothermal energy?
What are three sources of geothermal energy? Geothermal energy finds its way to the earth’s surface in three ways: Volcanoes and fumaroles (holes in the earth where volcanic gases are released) Hot springs. Geysers. How deep do you have to go for geothermal? For a horizontal loop you only need to dig between 6 – […]
