Mechanical waves need a medium to travel in
Radiation doesnt need a medium because it travels through space
They do not need a medium.
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.
no
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
Radiation doesnt need a medium because it travels through space
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
They do not need a medium.
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 .

The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
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. Electromagnetic waves travel through vacuum ( ie space where there is nothing)
Yes.
no
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.
Sound waves need a medium in order to propogate. Light waves can travel without a medium. The speed of light is 3*108m/s.
