Mechanical waves
All waves require a medium.
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
generally electromagnetic wave does not require any medium while sound waves require a medium (air) for propagation
No.
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.
Yes, earth is the 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.
(1) Electromagnetic waves, (2) gravitational waves.
Mechanical waves, such as sound waves and seismic waves, require a material medium (solid, liquid, or gas) to travel through. These waves propagate by transferring energy from one particle to the next within the medium.
Electromagnetic waves, such as light waves and radio waves, do not require a medium to travel through. These waves can travel through a vacuum, unlike mechanical waves which require a medium to propagate, like sound waves in air or water waves in the ocean.
A mechanical wave generally does NOT require a medium to propagate.
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.
