Hypernyms ("electromagnetic wave" is a kind of...):
radiation (energy that is radiated or transmitted in the form of rays or waves or particles)
Meronyms (parts of "electromagnetic wave"):
photon (a quantum of electromagnetic radiation; an elementary particle that is its own antiparticle)
Hyponyms (each of the following is a kind of "electromagnetic wave"):
