If we compare and contrast electromagnetic waves with sound waves, all BUT one statement is true. That is

• sound waves require a medium to travel while electromagnetic waves do not.

• electromagnetic waves can travel through the vacuum of space while sound waves cannot.

• electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere.

• sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
