1. What is the definition of medium?A substance or space through which energy or waves propagate
2. What is the technological applications?Fiber optics, wireless communication, ultrasound, and acoustics all rely on understanding mediums
3. What is a medium in physics?A medium is the substance that lets a wave or signal travel, like a road for a wave. It can be a solid, liquid, gas, or even empty space for light. The medium’s characteristics decide how fast the wave moves and how strong it is.
4. Why does sound travel faster in steel than in air?Sound moves faster in steel because steel is denser and more elastic than air. The particles in steel can push each other quickly, so the sound travels faster.

Wave Propagation: The process by which waves travel through a medium or space, transferring energy.
Luminiferous Aether: A hypothetical medium once thought to permeate all space and carry light waves.
Refractive Index: A measure of how much light bends when passing from one medium to another.
Attenuation: The gradual loss of intensity or amplitude of a wave as it travels through a medium.
