Random Question about Vibration

  1. Jan 8, 2014 #1
    Does skin vibrate at the molecular level?
    If so does it have a steady frequency?
    If so would it be possible to use a laser to detect said vibration from a distance?

    Yes, your skin does vibrate at the molecular level due to thermal energy but it does not have a steady frequency. Note that your skin does not vibrate like a drum does, with the entire surface moving together. Instead the individual atoms and molecules vibrate on their own.

    I don't see any way of using a laser to measure the vibration of the atoms or molecules of your skin. Atoms and most molecules are simply far too small for a laser measure.

    Use a thermal imaging camera?
