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 is the speed of electromagnetic waves in air?
About the same as in a vacuum - 300 million meters/second.
When electromagnetic energy travels from air into water the waves are bent due to the density differences between the air and water what is this bending called?
That is called "refraction".
What are energy waves moving through the air?
the answer is sound for all those of you that have trouble with science
What is the medium for the waves?
Anything that "transports" the wave. The specific medium depends on the type of wave; a water wave travels through water, a sound wave through air (or other material), electromagnetic waves, as well as gravity waves, can travel through empty space.f
What happens to the speed of electromagnetic waves when they go from air to water?
Since water is a substance of higher refractive index than air, therefore then speed of light decreases as it enters water.
What speed do television waves travel in air?

Electromagnetic waves travel faster over land or water?
as long as they are both traveling through the air, then the speed is the same.
What is the speed of electromagnetic waves in air?
About the same as in a vacuum - 300 million meters/second.
How do the velocities of a sound wave and electromagnetic wave compare to each other?
In air at sea level, the speed of electromagnetic waves isroughly 882 thousand times the speed of sound.
What is the speed of an electromagnetic wave with a frequency of 9.17 1016 Hz and a wavelength of 3.27 nm?
The speed of any wave is the product of the frequency and the wavelength. Be sure to convert the nm to meters first (dividing by 1,000,000,000). - By the way, in a vacuum, all electromagnetic waves travel at the same speed, known as the speed of light - about 300 million meters/second. However, in other substances - such as air, or water - electromagnetic waves are slower.
Name four media that waves can travel?
Electromagnetic waves: no medium requiredMechanical waves, such as sound: Air, water, steel, jello
Do all em eaves travel at the same speed?
Electromagnetic waves have the same speed when travelling through a given medium: Air, water, vacuum,...
Can electromagnetic spectrum waves travel through air?
Yes. Electromagnetic spectrum waves reach your eye through the air.
How does electromagnetic waves travel?
It depends on what they're traveling through. If they're traveling through vacuum, then it's what we call the "speed of light" but it's really the speed of all electromagnetic waves: 299,792,458 meters (186,282 miles) per second. If they're traveling through some material substance, such as air, water, glass, jello, etc., then the speed is a little less.
What speed do radio waves travel in air?
Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light (186,000 miles per second). The only difference between them is their frequencies (or wavelengths)
When electromagnetic energy travels from air into water the waves are bent due to the density differences between the air and water what is this bending called?
That is called "refraction".
