liquid
Copper is opaque to light - light can not travel though it.
Yes, but sound can not.
Light travels faster through liquid than through solid. The speed of light in a medium is determined by the refractive index of the material, which is lower in liquid compared to solid materials.
No. Light can travel in a vacuum.That's why we can receive light from sun even though there exists a vacuum in between Earth and sun.
Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio. Radio waves and light waves can travel through space, that is why we are able to receive light from the sun. Source: www.examville.com
The speed of light in a liquid depends on the properties of the liquid, such as its density and refractive index. In general, light travels slower in liquids compared to its speed in vacuum, which is approximately 299,792 kilometers per second. The exact speed of light in a specific liquid can be calculated using the formula v = c/n, where v is the speed of light in the liquid, c is the speed of light in vacuum, and n is the refractive index of the liquid.
Light, radiation, radio waves.
Mercury is reflective in its liquid form.
Plasma is the light yellow liquid in which red and white blood cells and platelets are suspened. it also dissolves the nutrients that travel in blood.
No, radiation does not require a heated liquid to transfer energy. Radiation can transfer energy through electromagnetic waves, such as ultraviolet light or x-rays, without the need for a medium like a liquid.
I wouldn't say to well
