What Requires A Physical Medium In Which To Travel?

The wave that requires a physical medium to travel in is (b) sound.

Sound requires air for the signal to travel in.

In fact, sound is defined as “vibrations of air”.

In contrast, light and other forms of electromagnetic waves do not need a medium to travel in.

Which wave requires a physical medium through which to travel?

Mechanical Wave – A wave that requires a physical medium through which to travel.

Which of the following are waves that 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.

Why does sound require a medium to travel?

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.

What is required for a sound wave to travel?

So, sound needs a physical medium in order to travel anywhere. The speed of a sound wave depends upon the medium through which it travels. In general, sound travels faster through solids than through liquids or gases. Also, the denser the medium, the slower sound will travel through it.

Does sound require a medium?

Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.

Do all waves require a medium?

All waves can be categorized as either mechanical or electromagnetic. 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.

What are the two types of waves?

There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves. The animations below demonstrate both types of wave and illustrate the difference between the motion of the wave and the motion of the particles in the medium through which the wave is travelling.

How do waves travel?

Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward. Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves.

Do radio waves travel forever?

The earliest radio waves emitted from earth are currently about 200 light years away. However as mentioned before they will keep going forever getting harder and harder to detect as time passes. They will travel forever radiating from the Earth at the speed of light.

Does light needs a medium to travel?

We know that light doesn’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).

How can you prove that sound needs a medium to travel?

The bell jar experiment is a common experiment used to demonstrate that sound needs a medium to travel. A bell jar is a laboratory equipment used for creating a vacuum. It is so named as its shape is similar to that of a bell.

Does sound travel faster in water or air?

Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster.Travel
