Can someone explain to the relationship between EMF radiaition and sound waves in a brief summary please?
What is vibrating?Sound waves are carried as a physical vibration of matter particles (atoms and molecules). If a sound reaches a place where there are no molecules (such as the edge of space), it dies out.Electromagnetic radiation is carried as an oscillation of electric and magnetic fields. It does not need any matter to vibrate, and travels quite well through a vacuum. That is why we can see the Sun and other stars.Types of Vibration?In a gas, sound waves are carried as a longitudinal vibration, with the atoms moving backwards and forwards in the direction that the sound wave is traveling. Electromagnetic waves have the electric and magnetic fields at right angles to each other, and at right angles to the direction of travel.In a solid, it is possible to have sound waves that vibrate at right angles to the direction of travel.
