Question 3Radio waves, a type of electromagnetic wave, are emitted by an antenna, picked up by a receiver, and translated into sound waves. Electrons in the antenna oscillate creating the radio waves, and these oscillations are decoded by the receiver to create sound waves in the range of human hearing. This concept is similar to having two aluminum cans connected by a string and sound is transmitted as vibrations in the string.Which statement describes a similarity shared between electromagnetic and mechanical waves?A    Electromagnetic and mechanical waves are both transverse waves.    B    Electromagnetic and mechanical waves are both caused by vibrations.    C    Electromagnetic and mechanical waves both need a medium to travel through.    D    Electromagnetic and mechanical waves both travel fastest through high density mediums such as solids.
