So electromagnetic wave is a non-mechanical wave. The speed of propagation of electromagnetic waves. Light, heat, radio, and similar types of energy are carried by a variety of waves in the ELECTROMAGNETIC SPECTRUM. Speed of mechanical waves are low and depends upon the source and the medium through which they travel. Light . 00:56. Ask yourself this: Why is it that a bullet can travel through a vacuum, but ocean waves require an ocean? Swing of the electric and magnetic fields perpendicular or right angle to each other forms the electromagnetic waves. Mechanical waves are unable to travel through a vacuum. A mechanical wave requires an initial energy input. Electromagnetic waves are waves which can travel through the vacuum of outer space. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium. 3. Mechanical waves are produced when particles vibrate in a medium in which the wave propagates. Matter waves require a medium to for propagation. Also asked, do all transverse waves need a medium to travel through? Light waves are electromagnetic or transverse waves consisting of varying electric and magnetic fields. Recommended Videos. such as radio waves. Sound can leap across a vacuum after all. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. Other wave types cannot propagate through a vacuum and need a transmission medium to . Write the difference Light contrasts with sound, which travels through the air (or some other material medium).
