Respuesta :
They travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space. Hence, option C is correct.
What is an electromagnetic wave?
An electromagnetic wave (radiation) can be defined as a type of wave that does not require any medium for its propagation. Also, light energy is a good example of an electromagnetic wave (radiation).
Electromagnetic waves are used in science as a propagating medium used in all communication processes device to transmit data from the device of a sender to the device of the receiver.
Hence, they travel at the speed of light, they include ultraviolet waves, and they can transfer energy through empty space.
