Answer: The correct answer is electromagnetic wave.
Step-by-step explanation:
In the electromagnetic wave, both magnetic field and electric field are perpendiculars each other to the direction of the motion of the wave.
Electromagnetic spectrum is the range of frequencies of electromagnetic radiations.
Microwave is an electromagnetic wave. It falls in the range of electromagnetic spectrum between radio and infrared rays. It is a high bandwidth communication. It is used in RADAR and for heating purpose in microwave oven. Its frequency range lies between 300 MHz and 300 GHz.
Therefore, microwave is the type of electromagnetic wave.
