In a way, they don't. There is always a medium; though for some waves, this medium can be empty space.
Mechanical waves, such as sound waves and water waves, require a medium (solid, liquid, or gas) for propagation because they rely on the vibration of particles in the medium to transmit energy. Electromagnetic waves, like light waves and radio waves, do not require a medium to propagate and can travel through a vacuum.
No, fluids can transmit both transverse and longitudinal waves. In a fluid medium, such as water or air, the propagation of waves can involve both types of wave motion, depending on the properties of the medium and the nature of the disturbance causing the waves.
No, sound waves cannot transmit energy through empty space because they require a medium, such as air or water, to travel through. In the absence of a medium, sound waves cannot propagate and transmit energy.
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
Mechanical waves require a medium for their propagation whereas electromagnetic waves require a medium for their propagation.
The propagation of light waves in a vacuum is the movement of light waves through empty space. In physics, propagation refers to the transmission or spread of waves or energy through a medium. In this context, the propagation of light waves in a vacuum demonstrates the fundamental concept of how waves can travel through space without the need for a material medium.
Electromagnetic waves are the only form of energy that does not need a medium for propagation.
The electromagnetic energy density is the amount of energy carried by electromagnetic waves in a given space. The propagation of electromagnetic waves is the movement of these waves through a medium or vacuum. The energy density affects how the waves propagate, as higher energy density can lead to stronger and faster propagation of electromagnetic waves.
That sounds very much like sound waves. (unintentional pun)
Sound waves are mechanical waves that propagate through the vibration of particles in a medium. Without a medium, such as air, water, or a solid, there are no particles for the sound waves to interact with and transmit the vibrations, so the wave cannot travel. Sound waves need a medium to transfer energy and propagate.
Waves that transmit energy are called mechanical waves. These waves require a medium to travel through, such as water or air, and they transfer energy as they propagate. Examples include water waves, sound waves, seismic waves, and waves along a rope.
True. All waves, including electromagnetic waves, sound waves, and water waves, transmit energy as they propagate through a medium. This energy is carried from one place to another by the wave motion.
