Light travels through a vacuum, and through the densest metals (though not usually very far). But then gamma radiation and radio waves are examples of light...

The speed of light is constant in a given medium.
Light energy.
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
Light will not travel into silver.
No, apart from "spacetime". But it CAN travel through a medium such as air or glass.
Light can travel through vacuum, but it is not a medium.
Light can travel through a vacuum, which means it does not require a medium to propagate. This is explained by the wave-particle duality of light. While light behaves as a wave and doesn't need a medium, it can also be understood as a stream of particles called photons.
Yes, light can travel through space because it does not need a medium to propagate.
Yes, light waves can travel through air because air is a medium through which electromagnetic waves can propagate. Light travels at different speeds through different mediums, but it can definitely travel through air.
Sound requires a physical medium, such as air, water, or solids, in order to travel because it propagates through vibrations of particles in the medium. On the other hand, light does not require a physical medium and can travel through empty space as electromagnetic waves.
Light waves do not need a medium to propagate. Sound waves cannot travel without a medium. Light waves always travel at the speed of light that is 3*108m/s.
When light is transmitted through a medium, it means that the light passes through the substance without being absorbed or reflected, allowing it to travel through the material.
Yes, transverse waves require a medium to travel through. Examples include water waves, which need water as a medium, and electromagnetic waves such as light, which can travel through a vacuum.
Sound waves require a medium to travel through, such as air, water, or solids, and they propagate by causing particles in the medium to vibrate. Light waves, on the other hand, can travel through a vacuum and do not require a medium. They propagate as electromagnetic waves and can travel through empty space.
Unlike waves in water, for example, light waves don't require a medium at all. They can (and do) travel through a complete vacuum, for example. If you'd like to read about this, the wikipedia article on light, and also on 'The Aether' will be of interest.
Sound and vibration are both mechanical vibrations of a medium, and thus demand a medium for their travel. Note- they vibrate the medium - they are not independent of the medium as is light.
