Quick Answer: Why do electromagnetic waves not require a medium to travel?

As I understand it, electromagnetic waves have two components which are the result of each other, i.e., when a moving electric charge creates a changing magnetic field at point X then a changing electric field is created at point Y and this repeating process is what creates EM waves, so therefore, it requires no medium …

Why do electromagnetic waves not require a medium?

Electromagnetic waves donot require any medium because they are composed of simply electric and magnetic field moving perpendicular to the direction of propagation of wave . They donot require any air particles as in sound waves for their propagation.

Why do electromagnetic waves not require a medium for travel quizlet?

Waves travels perpendicular of each other or right angles of each other. … Electromagnetic waves do not require a medium such as air, so they can transfer energy through vacuum, or empty space.

What electromagnetic waves require a medium to travel?

Propagation of an Electromagnetic Wave

Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves.

Do electromagnetic waves travel faster without a medium?

Because electromagnetic energy has no mass and travels at the speed of light. Even the speed of light and electromagnetic waves travel slower through a medium.

Do all waves require a medium to travel?

Yes, both mechanical and electromagnetic waves require a medium to propagate. Yes, all transverse waves require a medium to travel.

Do electromagnetic waves need a medium to travel through like mechanical waves do explain why or why not quizlet?

Light from the sun and stars could not travel through space to the Earth if light was a mechanical wave. Outer space is a vacuum so there is no medium for a mechanical wave to travel through. Electromagnetic radiation does not need a medium.

Do electromagnetic waves need a medium to travel through like mechanical waves do quizlet?

mechanical waves require a medium in which to travel. electromagnetic waves do not.

Which of the following is not an electromagnetic wave?

Sound wave is not an electromagnetic wave. It is a mechanical wave. When sound wave propagates, particles of the medium oscillates along the direction of propagation of the wave.

Do you not need any medium?

Answer: Electromagnetic waves ( e.g. light) do not require any medium.

Which of the following waves do not require any medium for their propagation?

Electromagnetic waves: The wave which is generated due to vibration between electric field and magnetic field and it does not need any medium to travel is called an electromagnetic wave.

Do mechanical waves require a medium?

Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles.

Why does an electromagnetic wave in space never slow down or speed up?

How is the fact that an electromagnetic wave in space never slows down consistent with the law of conservation of energy? If light slowed down, its energy would decrease, thereby violating the law of conservation of energy. … So light cannot travel slower than it does.”

Do electromagnetic waves slow down in a medium?

Yes, they slow down although at an extremely minuscule factor when traveling via ordinary materials. The observation that electromagnetic waves slow down significantly inside materials is because they interact with atoms strongly.
