Power is transmitted via radio waves for FM, AM radio, wifi, bluetooth, etc. Current is one component of power (you also need voltage). HV power lines transmit significant power in the electric field around the wires as well.

Can light be transmitted with or without a medium?

Light can be transmitted through a vacuum without the need for a medium, such as in outer space. However, in material mediums like air, water, or glass, light can also be transmitted through a process of absorption and re-emission of photons by the atoms in the medium.


Can electricity travel without a medium?

Normally electricity requires charge carriers that move through a medium. An alternating current can also travel - for short distances - through a vacuum, and WITHOUT charge carriers crossing the vacuum. To get more information, do some reading on capacitance and capacitors.


What does medium mean in science?

A medium is a substance in which a process occurs.


What does medium mean in science words?

A medium is a substance in which a process occurs.


Why doesnt a medium travel with the wave?

In wave motion, the medium does not physically travel with the wave because the medium particles only oscillate back and forth about their equilibrium positions. The energy of the wave is transferred through the medium by causing these particles to vibrate without displacing the medium itself.


Why medium was most difficult prepare without contamination why do you think this might be so?

Medium may be difficult to prepare without contamination because it is susceptible to airborne particles or microorganisms that can compromise its sterility. The complex mixture of components in the medium provides a rich environment for potential contaminants to thrive. Additionally, the process of preparing medium usually involves multiple steps and transfers, increasing the opportunities for introducing contaminants.


What are electrons flowing through a conducting medium is called?

"current"


What can travel through space without a(n) medium?

Electromagnetic waves can travel through space without a medium.


What is transmission in the context of science waves?

Transmission in the context of science waves refers to the process of waves passing through a medium, such as air or water, without being absorbed or reflected. This allows the wave to continue propagating through the medium.


What can be transmitted with or without a medium?

light


What is a wave without a medium?

A wave without a medium is an electromagnetic wave, such as light or radio waves, which can travel through a vacuum because they do not require a material medium for propagation.


Can a tranverse wave propogate without a medium?

No, a transverse wave requires a medium to propagate because the particles in the medium must move perpendicular to the direction of the wave's energy transfer. Without a medium, such as in a vacuum, transverse waves cannot propagate.
