Because something must move, in some sense, to transmit the wave. In a vacuum there is nothing capable of transmitting mechanical movement.
No, a transverse wave does not need a physical medium to travel. Transverse waves are characterized by perpendicular oscillations of the medium, and they can propagate through a vacuum or empty space as seen in electromagnetic waves.
Mechanical waves require a physical medium to propagate, such as sound waves in air or water waves in the ocean. Electromagnetic waves, on the other hand, can travel through a vacuum and do not need a medium. They include light waves and radio waves.
No, not all waves require a medium to travel through. Electromagnetic waves, such as light, can travel through a vacuum because they are composed of oscillating electric and magnetic fields rather than requiring a physical medium.
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
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.
Mechanical waves, such as sound waves, require a medium to travel through. These waves propagate by causing particles in the medium to vibrate and transfer the energy of the wave. Electromagnetic waves, such as light waves, do not require a medium and can travel through a vacuum.
Mechanical waves.For example, sound waves, ocean waves, etc.Many waves need a medium to travel: sound waves, water waves, and seismic waves.Electromagnetic waves do not need a medium.
No, longitudinal waves do need a medium to transport energy. These waves propagate by compressing and rarefying the medium in the direction of the wave's travel, and they cannot travel through a vacuum. For example, sound waves in air are longitudinal waves that require the air medium for propagation.
Electromagnetic waves do not require a medium to travel because they are fluctuations in electric and magnetic fields. On the other hand, sound waves are mechanical waves that need a medium, such as air, water, or solids, to propagate because they rely on the vibration of particles in the medium to transfer energy. This is why sound cannot travel through the vacuum of space.
Yes, it travels in waves, but it doesn't need a medium.
no
Two waves that do not require a medium to travel would be light waves and gravitational waves. - Zach Harris, B.S. Physics
