Mechanical waves require a medium, as opposed to electromagnetic waves which can travel through a vacuum.
Those waves which required medium for propagation are called mechanical waves. e.g sound waves,they need medium i.e solid liquid or gas ,to propagate. They cant travel through vacuum. hope u understand that!!
The only kind of wave that does not require a medium to pass through is an electromagnetic wave. These waves can travel through empty space and do not need a material medium for propagation. Examples of electromagnetic waves include light waves, radio waves, and X-rays.
Both P-waves (primary waves) and S-waves (secondary waves) can travel through solid and liquid materials. However, S-waves cannot propagate through liquids as they require a solid medium for transmission.
Mechanical waves, such as sound waves and ocean waves, require a medium (solid, liquid, or gas) to propagate. Electromagnetic waves, including light waves and radio waves, do not require a medium and can travel through a vacuum.
light waves
electromagnetic waves
Electromagnetic waves don't need anything to travel. This kind of waves does not need a medium to move through, therefore they can even travel through outer space.
Mechanical waves, such as sound waves and water waves, require a medium (solid, liquid, or gas) to travel through. Electromagnetic waves, like light and radio waves, do not require a medium and can travel through a vacuum.
Sound waves, they need a medium to vibrate.A2. Earthquake waves and other mechanical waves also need a medium for their transmission.Ghv. Tsunamis are a type of mechanical wave, which is the kind of wave you're looking for.
Because S waves are transverse waves and they can't travel through a liquid. This means that Zone C cannot be a liquid. By .:SCs~Blood+:.

P-waves, also known as primary waves, travel faster in a solid compared to S-waves, secondary waves. P-waves are compressional waves that can travel through both solid and liquid layers, while S-waves are shear waves that can only propagate through solid materials.
