Liquid
The material through which waves travel is called a medium. This could be a solid, liquid, or gas.
Surface waves
They travel through a material medium.
medium
Electromagnetic Waves can travel through space without any material medium.
Sound waves travel through a medium, such as air, water, or a solid material like metal or concrete. The medium acts as a carrier for the sound waves to propagate.
No, S-waves (shear waves) and P-waves (primary waves) do not travel at the same velocity in the same material. P-waves, which are compressional waves, move faster than S-waves because they can travel through both solids and fluids, while S-waves can only travel through solids. The velocity of these waves depends on the material's properties, such as density and elasticity, resulting in different speeds for each wave type.
Sound waves can travel through any compressible material (which means any real material), be it solid, liquid, or gas. Sound waves cannot travel through a vacuum.
The very name "mechanical waves" indicate that these need badly a material medium such as air, water etc.
Sound creates waves in a material- compression waves. These waves are transmitted through the atoms/molecules in the material to the receiver. The denser a material is, the more effectively sound may travel; this is because the sound waves are transmitted more easily through the tightly packed molecules.
The relationship between the wavelength in a dielectric material and the propagation of electromagnetic waves is that the wavelength of electromagnetic waves decreases when they travel through a dielectric material compared to when they travel through a vacuum. This is due to the slower speed of light in the dielectric material, which causes the waves to be compressed and have a shorter wavelength.
Electromagnetic waves, such as light and radio waves, can travel through space because they do not require a medium to propagate. These waves can travel through the vacuum of space and do not need a material substance to carry them.
