No, they are Electromagnetic waves and can travel through a vacuum. They do not need a medium.

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/sec in a vacuum.

Yes, it travels in waves, but it doesn't need a medium.

Some waves called mechanical waves e.g sound need a medium to travel through while electromagnetic waves need no medium to travel through e.g light

No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.

Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.

Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.

Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.

They dont need it, but they can use it

Sound waves need a medium like air or water. At 20&deg;C the speed of sound is 343 m/s. Light waves need no medium. In vacuum the speed of light is c = 299,792,458 m/s.

light; all waves in the EM(electromagnetic) spectrum, including visible light, do not need a medium to travel in

Two waves that do not require a medium to travel would be light waves and gravitational waves. - Zach Harris, B.S. Physics

Sound and water waves are mechanical and therefore need a medium. Light is an electromagnetic wave which travels as a particle-wave, so it does not need a medium to travel through.

No. light waves required no medium for transmission.

Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).

Mechanical waves such as sound and vibration require a medium in which to travel. Electromagnetic waves such as radio and light need no transmission medium.

No. Light is in the EM spectrum, and we can see light from the sun as space is a vacuum it can be concluded that EM waves do not need a medium.

Sound waves, ocean waves and seismic (earthquake) waves need a medium

Waves in water must be carried by water--i.e. water is the medium. Sound waves must be carried by a medium--i.e. air or water. This is why in space, without the medium of air, there is no sound. Electromagnetic waves--light waves--need no medium.

sound waves, water waves, shockwaves need mediums. Electromagnetic waves do not need a medium

Sound waves must travel through a medium, light does not require a medium. Sound waves are longitudinal waves, light are transverse waves.

Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .

Mechanical waves need a medium to travel in

Light travels in a vacuum as waves of photons. They do not need a medium in which to travel.

Light waves are not mechanical waves. This means that it does not need a material medium as an essential entity to get propagated through. But sound waves need some material medium such as air, water or even solid metals. Water waves badly needs water surface.Light waves has incredible speed but the other two are not so
