Sound travels at approximately 1,100 feet per second (766 miles per hour).
Radio waves travel at the speed of light, which is approximately 186,000 miles per second.
What wave travels faster than sound?
Light waves
travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. (Actual speeds are on the 2

What is the difference between radio wave and sound wave?
The main difference between radio waves and sound waves is that
radio waves are a type of electromagnetic wave that can travel when there is no medium, whereas sound waves are a type of mechanical wave that cannot travel if there is no medium
.
How quickly do radio waves travel?
Like all waves of the electromagnetic spectrum, radio waves travel
at the speed of light
. The speed of light in a vacuum is 299,792,458 meters per second, often approximated simply as 3 x 108 m/s.
Do all radio waves travel at the same speed?
All of these electromagnetic waves (whether radio, visible or gamma) travel at the same speed
. They all travel at the ‘speed of light’ through a vacuum, that is at 3 × 10

How does sound travel on a radio wave?
You can tune a radio to a specific wavelength—or frequency—and listen to your favorite music. The radio “receives” these electromagnetic radio waves and converts them to
mechanical vibrations in the speaker
to create the sound waves you can hear.
What type of wave does sound travel in?
Sound waves in air (and any fluid medium) are
longitudinal waves
because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.
Where does sound travel fastest?
Sound waves can only travel through a solid, liquid or gas medium. They travel fastest
in solids
, then liquids and slowest in gases.
When did the sound travel fastest slowest?
The speed of sound depends on the medium in which it is transported. Sound travels
fastest through solids, slower through liquids and slowest through gases
.
Which of the following travels the fastest?
Solution :
Light
is the fastest among all and according to scientists nothing can travel faster than light. The speed of light is.
Do radio waves travel the speed of light?
Like all electromagnetic waves,
radio waves in a vacuum travel at the speed of light
, and in the Earth’s atmosphere at a close, but slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents.
Are radio waves light speed?
Radio waves are a form of EMR—electro-magnetic radiation, the same as light. Thus,
they both travel at light speed (299,792.458 km/hr)
. Thus, sound carried by radio wave (299,792,458 m/s) will reach you much faster than sound that travels simply as a standard sound wave (343 m/s).
Why can radio waves travel longer distances?
It is
due to the Ionosphere
. Consider that optical wavelengths and shorter can propagate astronomical distances … if there is line of sight. Ditto VHF where FM is broadcast. But the ionosphere extends “line of sight” by reflecting the AM and short wave bands.
Why do all sound waves travel at the same speed?
Review: The speed of sound is faster in solid materials and slower in liquids or gases.
The speed of a sound wave is related to the elastic properties and density of the medium it is in
. Elastic properties relate to the tendency of a material to maintain its shape and not deform when a force is applied to it.
Are radio waves faster than microwaves?
I In air,
microwaves travel faster than radio waves
. II In air, microwaves have a longer wavelength than radio waves. III Microwaves and radio waves are both members of the electromagnetic spectrum.
Why do all waves travel at the same speed?
The speed of a wave is a product of its wavelength and frequency. Because all electromagnetic waves travel at the same speed through space,
a wave with a shorter wavelength must have a higher frequency, and vice versa
. This relationship is represented by the equation: Speed = Wavelength × Frequency.
Which wave has shortest wavelength?
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and
gamma rays
have the shortest wavelength.
What type of waves are radio waves?
Radio waves are a type of
electromagnetic radiation
best-known for their use in communication technologies, such as television, mobile phones and radios. These devices receive radio waves and convert them to mechanical vibrations in the speaker to create sound waves.
What affects the speed of sound as it travels?
The speed of the sound depends on
the density and the elasticity of the medium through which it travels
. In general, sound travels faster in liquids than in gases and quicker in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
What does the speed of sound depend on?
The speed of sound in air depends on
the type of gas and the temperature of the gas
. On Earth, the atmosphere is composed of mostly diatomic nitrogen and oxygen, and the temperature depends on the altitude in a rather complex way.
Does sound travel farther in air or water?
Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus
sound waves travel much faster in water than they do in air
.
What does sound travel the slowest through?
Answer and Explanation: Sound travels fastest when it is traveling through solids. When sound travels through
liquids, such as water
, it travels more slowly than when it is…
Do sound waves travel fastest in empty space?
Since a vacuum is empty space,
there is no medium for the sound to travel through
. The speed of sound in air mainly depends on the temperature of the air. On average, it is about 343 meters per second (1,125 feet per second), which is faster than the speed of sound in a vacuum.
Where sound waves Cannot travel?
Sound can not travel in
a vacuum
. A vacuum is an environment where liquids, gases, or solids of some sort are absent. If there are no objects then the sound waves do not have particles to vibrate, which means the sound waves can not travel.
