Answer:
They are contagious.
They are reflectible.
Matter can vibrate due to them.
They are capable of space travel.
Step-by-step explanation:
In contrast to mechanical waves, electromagnetic waves can travel without a medium. This implies that electromagnetic waves can pass not only through solid objects like air and rock but also through empty space.Charges that are oscillating (and radiate everytime they are accelerated) produce electromagnetic waves, which have the same frequency as the oscillation. It is typically a transverse wave because the electric and magnetic fields in the majority of electromagnetic waves are perpendicular to the direction the wave goes.
