Which wave requires a physical medium through which to travel?

Mechanical Wave

Which of the following requires a medium to travel?

Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.

What is a medium does sound need a medium to travel?

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter.

Is a medium required for light 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).

Can light travel in vacuum yes or no?

In contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. However, light can also travel within some materials, like glass and water.

Does light travel in straight lines?

Any physics student knows that light travels in a straight line. But now researchers have shown that light can also travel in a curve, without any external influence. Out in space, light rays passing near very massive objects such as stars are seen to travel in curves.

How do you know light travels in a straight line?

Light travels in straight lines Shadows are evidence of light travelling in straight lines. An object blocks light so that it can’t reach the surface where we see the shadow. Light fills up all of the space before it hits the object, but the whole region between the object and the surface is in shadow.

Can you slow down a photon?

Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass. However, it has generally been thought impossible for particles of light, known as photons, to be slowed as they travel through free space, unimpeded by interactions with any materials.
