Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. How do electromagnetic waves travel through different mediums? This is perhaps due to the fact that electromagnetic waves do Video Answer: Mayukh Banik. Electromagnetic waves can travel through a vacuum. We know that light doesnt need a medium to move because the speed of light is experimentally constant: independent of the motion of the source or detector or the direction in which it travels. Sound cannot travel in a vacuum because vacuum has no molecules that can vibrate and carry sound waves. 1 Why electromagnetic waves do not require a medium? Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum. Transmitters and receivers are usually built to work within a certain frequency range. Analytical cookies are used to understand how visitors interact with the website. A changing magnetic field creates an electric field, and vice versa, according to Maxwells equations. Radio waves have the longest wavelength. mechanical waves need a medium to travel through, electromagnetic waves do not. Examples: Radio waves, visible light, x-rays, etc . HIPAA privacy rule applies to the following. Mechanical waves move across a medium (such as air, water, glass, or rock). When an electromagnetic wave impinges upon the atoms of a material, the energy of that wave is absorbed. These variations in electric and magnetic fields fields lead to the transfer of the energy which is carried by the EM wave.
