Do light waves need a medium to travel through?

We know that light doesnâ€™t need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels. Light contrasts with sound, which travels through the air (or some other material medium). Which waves do not need a medium to travel through? Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves ...

What do waves need a medium to travel in?
• Sound waves and ocean waves are mechanical ones. Therefore, they need a medium to travel. Ocean waves are caused by energy shifting the water, while sound waves can travel through many mediums, including air and water. On the other hand, light waves are electromagnetic ones which can indeed travel without the help of matter. Other than light, this privilege also belongs to x-rays and radio waves.
Do all waves need a medium in order to travel?

light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters ...

Do you need a medium for sound waves to travel?
• Sound waves DO need a medium for transmission. But, different properties of various mediums make sounds travel at different speeds.

Technically yes they'll keep on traveling forever until they inevitably hit something. Long before that they will be so weak that they blend in with the background noise of the universe.

Do radio waves travel faster than sound waves?

Light waves and radio waves travel faster then sound waves. It has been know for thousands of years that you can see something happen in the distance before you hear it happen. Radio waves and light waves are both electromagnetic waves and both travel at the speed of light. The speed of a Radio wave is same as of Light and it is 3X108 meter /sec while sound travels with speed of 300 m/sec. In both cases, if the wave travels through a medium, the speed of the wave is reduced by the index of refraction. There is no normal medium where the speed of light could be altered to make it a million times slower or sound sufficiently faster to allow any electromagnetic wave travel more slowly than sound.

Can ocean waves travel without a medium?

Electromagnetic waves travel without a mediumâ€¦ Water and sound waves are mechanical and require a medium in order to travel. Light and radio waves are not mechanical but rather electromagnetic and do not need a medium.

In which medium does longitudinal waves travel?

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. A vibrating string can create longitudinal waves as depicted in the animation below.

In which medium sound waves travel faster?
• Sound travels fastest in solids and slowest in air. Water is in between. This is because the particles in solids are closer together than the particles in liquids or gases, and the particles in liquids are closer together than the particles in gases.
Light waves can travel without a medium?

Sir,light travels without medium (there is nothing between sun and earth) while the other two travel in mediums, sound in air water wave in water. Oh, thats not true light comes to earth and on earth it travels through air.

Light waves travel fastest in what medium?

Answer: The light travels fastest in Ice. Explanation: Refractive index is defined as the ratio of speed of light in vacuum to the speed of light in the medium. More the refractive index, less will be the speed and the light will travel slower and vice-versa.

What medium do longitudinal waves travel fast?
• Primary waves (also called pressure waves) are longitudinal in nature. They travel faster than other waves (up to 8 km/s in Earthâ€™s mantle and core, and 6 km/s in Earthâ€™s crust) and thus are the first signals detected on seismographs. P-waves can travel through solid rocks and fluids (liquid layers) of the Earth in a special pattern.
What medium do sound waves travel through?
• Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly.
What medium do waves travel fastest in?

Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.

What waves can travel without a medium?

So no medium, as in vacuum, means no waves of a medium, and therefore no sound. That's because sound is a mechanical wave. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.

What waves require a medium to travel?

Mechanical waves are waves that require a medium. This means that they have to have some sort of matter to travel through. These waves travel when molecules in the medium collide with each other passing on energy. One example of a mechanical wave is sound.

Which waves can travel without a medium?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Do radio waves travel the fastest?

Communications System

Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second.

Do radio waves travel the furthest?

Since radio frequency does not stop in a vacuum it it continues to travel there is no real farthest frequency. There are differences when you're thinking terrestrial frequencies and The general rule is the higher the frequency the shorter the range that it is able to be reliably received.

How far can radio waves travel?

Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz.

How fast do radio waves travel?

Follow Us: Radio waves travel at a velocity that is equal to the speed of light traveling in a vacuum, which is 186,282 miles per second. Top speed is only possible in empty space; passing through transparent liquids and solids like crystals cause waves to bend, which slows down their speed.

How fast to radio waves travel?

They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz. How do radio waves travel at the speed of light? Like all other electromagnetic waves, radio waves travel at the speed of light in vacuum.

How long will radio waves travel?

The distances to be traveled are so great that even light or radio waves take a while getting there. It takes around eight minutes for radio waves to travel from the Earth to the Sun, and four years to get from here to the nearest star.

Will radio waves travel in space?

Why does it take so long for the radio waves to travel through space? Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second.
