Hypernyms ("physical phenomenon" is a kind of...):
natural phenomenon (all phenomena that are not artificial)
Hyponyms (each of the following is a kind of "physical phenomenon"):
floatation; flotation (the phenomenon of floating (remaining on the surface of a liquid without sinking))
chop (the irregular motion of waves (usually caused by wind blowing in a direction opposite to the tide))
turbulence; turbulency (unstable flow of a liquid or gas)
transparence; transparency (permitting the free passage of electromagnetic radiation)
syzygy (the straight line configuration of 3 celestial bodies (as the sun and earth and moon) in a gravitational system)
surface tension (a phenomenon at the surface of a liquid caused by intermolecular forces)
fundamental interaction; interaction ((physics) the transfer of energy between elementary particles or between an elementary particle and a field or between fields; mediated by gauge bosons)
propagation (the movement of a wave through a medium)
conduction; conductivity (the transmission of heat or electricity or sound)
resolution ((computer science) the number of pixels per square inch on a computer-generated display; the greater the resolution, the better the picture)
resolution; resolving power (the ability of a microscope or telescope to measure the angular separation of images that are close together)
refraction (the change in direction of a propagating wave (light or sound) when passing from one medium to another)
reflection; reflexion (the phenomenon of a propagating wave (light or sound) being thrown back from a surface)

decalescence (phenomenon that occurs when a metal is being heated and there is a sudden slowing in the rate of temperature increase; slowing is caused by a change in the internal crystal structure of the metal)
electrical phenomenon (a physical phenomenon involving electricity)
electricity (a physical phenomenon associated with stationary or moving electrons and protons)
energy (any source of usable power)
energy; free energy ((physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs)
