All waves require a medium.
generally electromagnetic wave does not require any medium while sound waves require a medium (air) for propagation
No.
Yes, earth is the medium
A mechanical wave, such as a sound wave or water wave, requires a medium (substance) to travel through. In a mechanical wave, the energy is transferred through the medium by the vibration of particles.
A mechanical wave generally does NOT require a medium to propagate.
Mechanical waves
A wave without a medium is an electromagnetic wave, such as light or radio waves, which can travel through a vacuum because they do not require a material medium for propagation.
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.
No, radio waves are not mechanical waves. They are a type of electromagnetic wave that do not require a medium (such as air or water) for propagation. Mechanical waves, on the other hand, require a medium to travel through.
Mechanical waves require a medium for their travel.
A standing wave requires a relative motion of the medium at the same velocity of the wave
Mechanical waves, such as sound waves and water waves, require a medium to travel through. These waves rely on the vibration of particles in the medium to carry energy from one place to another. Electromagnetic waves, on the other hand, can travel through a vacuum because they do not require a medium.
