by admin. Mechanical vs Electromagnetic Waves. Mechanical waves end electromagnetic waves are two types of waves discussed in physics. Mechanical waves are waves that are caused by mechanical actions such as vibrations. Electromagnetic waves are waves created by oscillating electric and magnetic fields.
Rather, we are talking about the waves that transmit radio signals. The main difference between radio waves and sound waves is that radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium. What are Radio Waves. Radio waves are electromagnetic waves. These are waves composed of electric and magnetic fields, which are oscillating at right angles to each other. The energy of an electromagnetic wave propagates at a direction at right angles to the oscillations in both the electric and magnetic fields.
