That statement assumes that every wave needs a medium, which is a false assumption. An electromagnetic wave, such as light, does not need a medium.
An electromagnetic wave does not need a medium. It is able to pass through a vacumn.
Yes. Sound wave is a mechanical wave and needs a medium.
any wave of energy except for electromagnetic waves need a medium to travel through.
An electromagnetic wave does not need a medium through which to travel. This includes light, radio, TV, X-4ay, etc. The wave contains its own medium which is a photon.
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.

medium is the matter a wave trvels through
Waves do not need a medium all time.it depends like u need no medium when it is electromagnetic wave.
