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.
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.
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.
A mechanical wave generally does NOT require a medium to propagate.
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 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.
