What type of medium is required by light waves?
Unlike waves in water, for example, light waves don't require a medium at all. They can (and do) travel through a complete vacuum, for example. If you'd like to read about this, the wikipedia article on light, and also on 'The Aether' will be of interest.
What does sound have to travel through?
Sound and vibration are both mechanical vibrations of a medium, and thus demand a medium for their travel. Note- they vibrate the medium - they are not independent of the medium as is light.
When does light travel in a straight line?
travels through a uniform medium
Is light an example of mechanical wave?
No. Light is an example of an electromagnetic wave, which can travel through a vacuum. Mechanical waves must travel through a medium, and cannot travel through a vacuum.
Is medium required to transmit light waves?
No. light waves required no medium for transmission.
What waves need a medium to travel in?
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
What kind of wave does not need a medium through which to travel?
Electromagnetic waves do not require a medium to travel through. These waves consist of oscillating electric and magnetic fields and can travel through vacuum. Examples include light waves, radio waves, and X-rays.
Does light require a medium to travel through?
No, light doesn't need a physical medium, like air, to travel. As a matter of fact, light travels the fastest it possibly can, 2.98 * 10^8 meters per second, in a vacuum, like space. If light couldn't travel without a medium, then Earth wouldn't receive any light from the Sun.
Can light travel in a vacuum?
Yes. Light waves are electromagnetic waves, which do not require a medium to travel through.Mechanical waves (such as sound) do require a medium to travel through, so sound waves cannot travel through a vacuum.Space is a vacuum. The light from the stars (including our own sun) travel across a great distance in a vacuum to get to us.The accepted speed of light is its speed in a vacuum, which is 299,792,458 m/s.
Can light travel through outerspace?
Yes, light can travel through outer space because it does not require a medium to propagate. In the vacuum of space, light can travel almost undisturbed for long distances until it interacts with matter.
What wave doesnt require a medium to travel through?
Electromagnetic waves do not require a medium to travel through. They can travel through a vacuum because they consist of oscillating electric and magnetic fields. Examples of electromagnetic waves include light, radio waves, and X-rays.
A type of energy that travels as a wave but does not require a medium through which to travel?
Light energy.
