Why electromagnetic waves do not require a medium?
Out of the given waves , radio-waves are electromagnetic waves and all other waves are mechanical waves . Electromagnetic waves don’t require medium to propagate because they are formed by changing magnetic and electric field , and these fields don’t require any medium to propagate .
Do electromagnetic waves not require a medium for travel?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Why do electromagnetic waves not require a medium for travel quizlet?
Waves travels perpendicular of each other or right angles of each other. The energy that electromagnetic waves transfer through matter or space. Electromagnetic waves do not require a medium such as air, so they can transfer energy through vacuum, or empty space.
Why do waves need a medium to travel?
Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy.
