Light waves is the distance between two wave crests.
=============================
So you get the idea of light waves. Now these waves possess certain wavelengths. That is why we are able to perceive the various shades of colors. Light waves explain phenomenons like reflection, refraction, diffraction, interference, dispersion, etc. But there are some properties that cannot be explained by light waves such as scattering or shielding effect, Black body radiation,Compton effect,etc.(The last few terms are generally observed in the quantum world). These are explained by something called the particle nature of light waves. It is proven that light contains both waves as well as particle nature.
I like to end my discussion here because i do not know which standard you study in or are you a scientist. So the latter part of my discussion can be either alien to you or very disappointing(based on the fact that you are a first grader or a scientist respectively).

Quasars are among the strongest sources of?
Light and radio waves.
Why can astronauts not hear one another when traveling in space?
The light waves they reflect travel through empty space but sound waves do not.
In which type of wave does light travel?
All the electro-magnetic waves travel at the speed of light. Electromagnetic spectrum includes the following: * X-rays * Gamma rays * Ultraviolet rays * Infrared waves * Microwaves * Radio waves * Cosmic rays
What the similarities between echoes of sound and images in a mirror?
Echoes of sound and images in a mirror involves sound waves and light waves respectively being reflected off a surface.
What is a neutron star which emits radiation that reaches the earth as radio waves and flashes of visible light?
pulsar
Why does there have to be a medium for waves to travel through?
There does not have to be a medium. Light does not require a medium. Mechanical waves require a mediumAnswer 2:Not all waves require a medium for their transmission. Mechanical waves require a medium for their transmission because it is the molecules of the medium which cause the wave to propagate. However, electromagnetic waves do NOT require a medium. (for example light)
How can light waves move through space?
Light waves, unlike sound, do not require a medium.
What waves require a medium and what waves do not?
Mechanical waves require a medium (substance) to travel in, other waves do not. For example, sound is a mechanical wave and require a medium (air, water, etc.), light is not a mechanical wave and does not require a medium
Why light waves doesn't require a medium for its propogation but sound waves require?
sound waves move along with the particles of matter through which it passes
What is an example of a wave that doesn't require medium?
Electromagnetic waves, including light waves.
What is an example of a wave that doesn't require a medium?
Electromagnetic waves, including light waves.
What is a wave that doesn't require a medium for propagation?
Electromagnetic waves (like light) don't require a medium for propagation, unlike mechanic waves (like sound).
What two waves do not require a medium?
The two waves which do not require a medium are electromagnetic waves, also known as light and gravitational waves. Gravity waves have not been detected yet but are predicted by general relativity so are expected to exist.
Do Light Waves Require Mediums?
Light waves can travel through empty space. You might say that the empty space is the medium in this case.
Name one kind of wave that does not require a medium?
An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.An electromagnetic wave (this includes light) does not require a physical medium - it can travel through empty space.
Is a medium necessary for a wave to travel?
No not really. Sound waves are mechanical waves. They require a medium for propagation. On the other hand, Light waves are electromagnetic and do not require a medium. Hence you cannot hear in space. AND light waves reach the earth from the sun through space- which is a vacuum!!
Waves that do not not need a medium?
Two waves that do not require a medium to travel would be light waves and gravitational waves. - Zach Harris, B.S. Physics
