How are concave and convex mirrors similar?
They can be made from the same reflective material. They both are able to curve.
Can you see the reflective material without light and why?
well no as it bounces
A material that does not transfer heat very well?
Plastic Better materials to slow heat transfer through conduction are called heat insulation material, like fiberglass, foam, and historically, asbestos. A trapped air space is also very good, like double pane windows. But radiant heat is best insulated using reflective surfaces separated by a space. The lighter the density of the material between the reflective surfaces, the better the insulation effect. A vacuum between reflective surfaces is ideal. This is often called a thermos. This is what is used to store liquefied gases.
What material is the best absorber of infra-red radiation?
A black surface, indicating the surface is not reflective -- all lights are being absorbed -- visible or invisible.
What 2 conditions are essential for total internal reflection?
1 first medium has a larger reflective index than the second medium (means the first material is denser than the second material) 2 the angle of incidence must be larger than the critical angle
How are concave and convex mirrors similar?

What material will make you visible at night?
reflective gear such as reflective jackets ECT.
Why do curved mirrors obey the law of reflection?
they are made out of reflective material, and just reflect in a different direction
What is an example of reflective material?
mirror
Reflective material or products?
Polished glass formica
Can you see the reflective material without light and why?
well no as it bounces
What is the medium of a mirror?
The definition of "Medium" is the material that something is made of. So, a mirror can be made of any material that can be polished enough to be reflective. For example, Metal, Plastic, Glass, even Water can have mirror properties. You may wish to restate your question?
Do projectears work on white walls?
Yes, but they work best on silvery, reflective material.
What is a good bag to put band patches on. Need some sugestions please?
There are many good bags to put band patches on. Some suggestions for the bags are strong totes or backpacks. The bag needs to made from a thick material and not any type of vinyl bag.
Who made the first reflective telescope?
Isaac Newton in 1668Newton.
Which metal has highest reflective index?
i think aluminium, its the most common reflective one anyway. Actually I am in the middle of a project that requires this information. Silver exceeds aluminum. Silver has a 98% RI and Aluminum is 90%.
What is the reflective substance on workers' vests?
Those are microscopic beads of titanate glass, with a reflective material on the back half of each bead. They exhibit "retroreflectivity"- bouncing light back to the source of the light. When illuminated by headlights of a car, they bounce light back to the headlights. The best known brand is probably Scotchlite, made by 3M.
