Light travels slower through denser media, so it travels faster through water than through a diamond.
Sound waves travel faster through denser media, like solids, because the molecules are closer together, making it easier to pass the sound from molecule to molecule. Light and other electromagnetic waves travel faster through less dense media, and they travel fastest through a vacuum.
No, not all light waves that travel through a convex lens pass through the focal point. It depends on the wavelength of the light, since light of different wavelengths diffract at different angles when encountering a change in media, such as air to glass, at an angle. Isaac Newton noted this in his study of light and prisms.
The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.
Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.
Objects that allow most light to pass through are described as transparent. In contrast, translucent objects allow some light to pass through, but don't let you see objects. Opaque objects allow no light to pass through.
In reflection, the light waves travel within the same media and maintains the same speed but in refraction light waves travel through a different media and so their speed changes.

IT belongs to the Transmission media (Transparent media) it carries either data or audio/video files also.These are fairly used in light i.e it carries also light waves.

The molecules must be close enough to touch. They can travel through solids, liguids, and gases.
