Superconduction is a term that describes a material that has zero electrical resistance. This is significant because even good conductors like copper or gold always have some electrical resistance. Superconduction is an effect that only happens when particular materials are extremely cold (think liquid nitrogen). The effect is used in generating powerful magnetic fields in MRI machines. Optical conducting materials (also known as waveguides) are a material that transmit light using a process called total internal reflection. Optical fibre cable is a common example of an optical conductor.

What materials are optical lenses made from?
Plastic, glass, polycarbonate.
How would a superconducting material at room temperature be useful?
Most superconducting materials have to be very cold. Getting materials this cold tends to require the use of a lot of energy. The idea behind superconducting materials is to transfer energy more efficiently, without energy loss due to such things as heat. So, expending energy to save energy defeats the point. With a superconductive material at room temperatures, we could do things like send electricity for long distances without losing any of the electricity along the way. Electricity could be generated in wind farms on the plains and sent to houses on the coasts with no loss. It could make computers more efficient as well by allowing the creation of super-fast electronic switches. This is done by sandwiching a thin insulating layer between two pieces of superconductive material.
Light travels in a material with greater .......?
Optical Density. Which often is caused by normal density.
Does a superconductor expel a magnetic field?
As a superconducting material transitions into its superconducting state, it ejects internal magnetic fields. In that light, yes, a superconductor could be said to expel a magnetic field according to what is called the Meissner effect. A link can be found below.
What are the conditions for total internal reflection to occur?
It occurs when light traveling from one medium to another is completely reflected at the boundary between the two materials. The angle of incidence must be over a certain value (depending on the optical properties of the materials at the boundary).
When was Optical Materials created?
Optical Materials was created in 1992.
What are crystalline structures that conduct electricity without resistance when cooled to a certain temperature?
Superconducting materials.
What has the author Solomon Musikant written?
Solomon Musikant has written: 'Optical materials' -- subject(s): Optical materials
What is the second best conductor of electricity?
At ordinary temperatures, the element that's the best conductor of electricity is silver, with the second best being copper. At very low temperatures, some materials become superconducting. Superconducting materials are all perfect conductors of electricity, with no resistance at all.
How might consumers benefit from the use of superconducting materials?
by providing consumers and workers with jobs and new technology methods
What is some materials for the optical illusions?
hologram
