What else can I help you with?
Which property describes an electromagnetic wave and not a mechanical wave?
An electromagnetic wave does not require a medium to travel through, whereas a mechanical wave does. This property is known as the ability of an electromagnetic wave to propagate through a vacuum.
What is the disturbance that travels in a water and EM waves?
The disturbance that travels in a water and EM waves is sometimes known as electromagnetic radiation. Electromagnetic waves have the ability to travel through a vacuum.
How does electromagnetic energy travel through space?
Electromagnetic energy travels through space in the form of waves, known as electromagnetic waves. These waves consist of electric and magnetic fields that oscillate perpendicular to each other as they propagate through space. The energy is carried by these waves and can travel through a vacuum, such as outer space, without the need for a medium.
What are electromagnetic waves that can travel through space?
Electromagnetic waves that can travel through space are known as light waves or electromagnetic radiation. These waves consist of oscillating electric and magnetic fields that propagate through vacuum at the speed of light. Examples include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Why do light waves require a medium in which to travel?
Light waves do not require a medium through which to travel. They will travel (propagate) perfectly well in a vacuum. Otherwise, light would not pass through the vacuum of space. It would be very dark here on earth as the light from the sun, moon and stars could not reach Earth through the vacuum of space.
If someone asked you to prove that electro- magnetic waves travel in a vacuum what would you say?
Electromagnetic waves are known to travel through vacuum based on empirical evidence and theoretical knowledge in physics. This is supported by experiments such as the Michelson-Morley experiment and the behavior of electromagnetic radiation in space. Additionally, electromagnetism is a fundamental force in nature with well-established properties, including the ability to propagate through vacuum.
What speed do electromagnetic waves travel?
the speed of lightspeed of light
What speed do television waves travel in air?
If the information for television goes through the air, the waves used are electromagnetic waves; specifically of the type called RADIO WAVES.All electromagnetic waves travel at the speed of light when in a vacuum: about 300,000 km/second. In air, the speed is almost the same as in a vacuum.
What are disturbances that carry energy through matter?
These disturbances are known as "waves". Examples include compression waves in air or other media (i.e., sound), and electromagnetic waves, which can travel both through matter and through empty space.
Why are light waves are able to travel through vacuum?
Light "waves" are able to travel through a vacuum because light is only halfway "wavy". Light is actually a collection of particles, known as photons. Photons, because they are particles, are able to travel through a vacuum; unlike waves, they don't need a medium to travel from place to place. If you're interested in what I mean by "halfway wavy" look up the quantum particle-wave duality nature of light on Wikipedia.
What do you know about the speed of the 2 waves in the vacuum?
In a vacuum, electromagnetic waves (such as light) travel at a speed of approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is known as the speed of light and is the fastest speed at which energy, information, and matter can travel in the universe.
Does Electromagnetic Radiation travel through a medium known as the Aether?
No. The lumineferous Æther was assumed to exist, for as long as people were sure that waves needed something to carry them. But the Michelson-Morley experiment demonstrated that it doesn't exist, and electromagnetic radiation travels through a region that's full of truly nothing.
