Please help!!

Why do electromagnetic waves not require a medium for travel?

A)
because electromagnetic waves travel too fast for stationary particles to move with them


B)
because electromagnetic waves transmit energy without compressing the particles of the medium


C)
because electromagnetic waves generate their own particles for compression and use these for movement


D)
because electromagnetic waves move in two-dimensional space, the particles of mediums exist in 3-D space

Answer 1

B)

Electromagnetic waves do not require a medium because electromagnetic waves transmit energy without compressing the particles of the medium. Waves that compress particles are pressure waves like sound. Electromagnetic waves are light.
