Question

which are characteristics of electromagnetic waves? check all that apply. travel in straight lines and can bounce off surfaces travel through space at the speed of light travel only through matter travel only through space can bend around objects move by particles bumping into each other move by the interaction between an electric field and a magnetic field

Explanation:

Electromagnetic waves travel in straight - lines and can reflect (bounce off surfaces). They travel through space at the speed of light. They can also diffract (bend around objects) and are generated by the interaction between an electric and a magnetic field. They can travel through both matter and space and do not move by particles bumping into each other (unlike mechanical waves).

Answer:

travel in straight lines and can bounce off surfaces
travel through space at the speed of light
can bend around objects
move by the interaction between an electric field and a magnetic field
