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 else can I help you with?
What happens to the path of waves when they travel from air to water, and why does this change occur?
When waves travel from air to water, they change direction and speed. This change occurs because the speed of waves is determined by the medium they are traveling through, and water is denser than air, causing the waves to slow down and bend.
Do sound waves or light waves travel faster?
In air, light waves travel about 871 thousand times faster than sound waves.
Which phenomenon do em waves exhibit that sound waves do not?
Electromagnetic waves can travel through a vacuum, while sound waves require a medium (such as air, water, or solids) to propagate. Additionally, electromagnetic waves can travel at the speed of light, while sound waves travel at a much slower speed.
What happens to the path of waves when they travel from air to water?
When waves travel from air to water, they change direction and speed due to the difference in density between the two mediums. This causes the waves to bend or refract as they enter the water.
Is this true Light waves do not change speed as they travel from air through water?
Light waves do change speed as they travel from air to water due to the change in the medium's refractive index. In general, light travels slower in water compared to air, causing a change in speed and resulting in the bending of the light waves known as refraction.

Do sound waves or light waves travel faster?
In air, light waves travel about 871 thousand times faster than sound waves.
What is the speed of ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?
No, ultrasonic wave do not travel at all in a vacuum.
Which phenomenon do em waves exhibit that sound waves do not?
Electromagnetic waves can travel through a vacuum, while sound waves require a medium (such as air, water, or solids) to propagate. Additionally, electromagnetic waves can travel at the speed of light, while sound waves travel at a much slower speed.
What speed do sound waves travel at?
760 miles per hour (in air).
What speed do sound waves travel?
760 miles per hour (in air).
What happens to seismic waves in the air?
In air, the seismic waves(P-wave) are simply sound waves, and travel with the speed of sound (approx. 335 m/s).
What happens to the path of waves when they travel from air to water?
When waves travel from air to water, they change direction and speed due to the difference in density between the two mediums. This causes the waves to bend or refract as they enter the water.
What needs to travel through the air slowly?
An hot air balloon i think.

Where do the light waves change speed from a pencil?
Light waves change speed when they travel from air into the material of the pencil, and then change speed again when they exit the pencil back into the air. This change in speed causes the light waves to refract or bend.
Is the speed of a sound wave slower than a electromagnetic wave?
Yes, the speed of sound waves is slower than the speed of electromagnetic waves. Sound waves travel through a medium, such as air or water, at a speed that depends on the properties of that medium. Electromagnetic waves, such as light, can travel through a vacuum at a speed of about 300,000 kilometers per second.
