The case surrounds the question of whether or not William Marburyâs right to a commission is valid and if he is due a mandamus from the court.
An electromagnetic (EM) wave is not a sound wave. A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy. The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields. This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.
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. The energy of the mechanical waves depends on the amplitude of the wave, but the energy of an electromagnetic wave depends only on the frequency. â¢ Electromagnetic waves display particle like behavior, but mechanical waves do not display such behavior.
