no they do not have a medium.
No. light waves required no medium for transmission.
Light waves are electromagnetic waves that move at the speed of light. Sound waves are compression waves that move through a medium (air, liquids, solids), with varying speeds according to the medium.
Yes, it travels in waves, but it doesn't need a medium.
No medium is required by electromagnetic waves to traverse.
When all of the energy from light waves is transferred to a medium, it is absorbed by the medium. This absorption can result in the medium heating up, causing a temperature increase. The energy of the light waves is converted into thermal energy within the medium.
Mechanical waves require a medium (substance) to travel in, other waves do not. For example, sound is a mechanical wave and require a medium (air, water, etc.), light is not a mechanical wave and does not require a medium
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.
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
When light waves pass from one medium to another, they may be refracted, reflected, or both. Refraction occurs when the speed of light changes as it enters a new medium, causing the light to bend. Reflection occurs when the light waves bounce off the surface of the new medium.
light waves do not need a medium. Electromagnetic Waves (EM) do not need a medium. For example visible light, radio waves, microwaves, UV light and x-rays do not. These travel @ 300 million meters/sec in a vacuum.
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.
Light waves are eletromagnetic waves and sound waves are mechanical waves. Additionally, a light wave is a transverse wave that does not require a medium through which to travel. Sound waves, on the other hand, are longitudinal waves where the source transfers the mechanical energy of the sound wave into the medium so it can travel.
