Physics Quiz Answers

  1. phosphorescence
  2. Graviton ( None of the Above)
  3.  Instantaneously
  4. Fluoroscence
  5. Gluon

Physics Quiz Explanation:

  1. About Phosphorescence
    Explanation:
    Well you can see this phenomenon in your everyday
    life. It’s present in the dark toys or clock dials that
    tend to glow when the room or surrounding
    becomes totally dark, but it’s the phenomenon that
    occurs when you charge them with really bright
    lights. That’s called phosphorescence i.e. emission of
    light of one color from a body after it is exposed
    to another color of light.
  2. Which is hypothesized to be mediating
    gravitational interaction?
    Explanation:
    The answer isn’t present in the options. Option A
    Photon is the particle that mediates electromagnetic
    interaction. Neutrino and Higgs boson don’t
    mediate any interaction. It’s Graviton that is
    hypothesized to be mediating the gravitational
    interaction. It’s not sure yet. The particle must be
    traveling with the speed of light.
  3. About Photoelectric effect:
    Explanation:
    In the photoelectric effect, electrons are emitted at the
    instant energy or photon is incident on the
    photoelectric surface. Photons transfer their kinetic
    energy to electrons on the surface and
    instantaneously electrons get out of the surface.
  4. About Florence:
    Explanation:
    It’s a property of a body by which the body absorbs
    light of short wavelength and emits light of longer
    wavelength.
  5. Which particle won’t be deflected by an
    electromagnetic field?
    Explanation:
    The first option is Gluon which has a charge of 0. So it
    won’t be deflected by the electromagnetic field. Now
    we just can’t choose option A. So, go to the next option which says “All of
    the above”. So next is Muon. It has an Electric charge −1 e. W Boson has
    charge ±1 e. So both will be deflected by
    the electromagnetic field. So the answer is Gluon.
    Som Abhishek.
