Waves are a type of disturbance that travel through space and time, carrying energy from one place to another. The way waves are transmitted depends on the nature of the medium they travel through.
In a medium, such as a solid, liquid, or gas, waves are transmitted through the vibration of particles in the medium. When a wave travels through a medium, it causes the particles in the medium to vibrate in a particular way, transferring energy from one particle to the next. These vibrations then travel through the medium, carrying the wave along. The speed of the wave through the medium depends on the properties of the medium, such as its density, elasticity, and viscosity.
In a vacuum, which is an empty space without any material medium, waves are transmitted differently. There are electromagnetic waves, such as light and radio waves, that can travel through a vacuum. These waves are not transmitted through the vibration of particles in a medium, but rather through oscillating electric and magnetic fields that propagate through space. They do not require a medium to travel through, and can travel through the vacuum of space at the speed of light.
In summary, waves are transmitted through a medium by causing the particles in the medium to vibrate, while waves in a vacuum are transmitted by the propagation of electric and magnetic fields through empty space.
