Refraction is the bending of the rays of light when it travels from one medium to another... For refraction to occur there should be some difference in the refractive index of the materials.... Refraction can also occur in Opaque medium........
In denser medium,particles of matter are very close to each other.whereas,in rarer medium,particles of the medium are slightly farther apart.
No medium is required by electromagnetic waves to traverse.
A medium is a substance in which a process occurs.

A sound wave travels through a medium because the particles in the medium vibrate when the wave passes through, passing on the energy and disturbance from one particle to the next through collisions. This creates a chain reaction that allows the wave to propagate through the medium.
False. The denser the medium, the faster a transverse wave propagates. This is because denser mediums have a higher resistance to deformation, which allows the wave to travel more quickly through them.
In general, the speed of a wave is faster in more elastic mediums because the elasticity allows the wave to propagate more quickly through the material. This is because in more elastic mediums, the particles can easily return to their original position after being displaced by the wave, facilitating the propagation of the wave at a faster rate.
Charcoal and chalks are two that easily smudge, as the powder is not held within a binding medium, such as oil-paints and watercolours.
The speed of sound in a medium is determined by the density and elasticity of the medium. In general, sound travels faster in solids because they have higher densities and elasticities compared to liquids and gases. This allows the sound waves to propagate more quickly through the medium.
it allows sound to go through it
Baseband
A medium that allows only liquids to pass through it is called an "impermeable medium." This means that it restricts the flow of gases or solids while enabling the movement of liquids.
