Refractive index is a scalar quantity because it describes how light propagates through a medium by bending, or refracting, without considering a specific direction of travel.
Light is a form of electromagnetic radiation that can travel through a vacuum, or a space with no air, meaning it does not require a medium to travel through. Other forms of electromagnetic radiation, like radio waves, microwaves, and x-rays, can also travel through a vacuum. Sound, on the other hand, is a form of mechanical wave which requires a medium to travel. This medium can be a solid, liquid, or gas, and is the way sound travels from one place to another. For example, when someone speaks, the sound waves travel through the air and reach our ears. In summary, light and other forms of electromagnetic radiation can travel with or without a medium, while sound requires a medium to travel.
Sound waves are mechanical waves, which means they require a medium, such as air or water, to travel through.
No, sound cannot travel through a room with no air because sound waves need a medium, such as air, water, or a solid, to propagate. Without a medium, there is nothing for the sound waves to travel through.
Sounds need a medium to travel, such as air, water, or solid materials. As sound waves pass through the medium, they cause particles to vibrate, transmitting the sound energy from one point to another. Without a medium, such as in a vacuum, sound waves cannot travel.
