What are transparent, translucent and opaque materials?
2017年5月15日 · Transparent, translucent and opaque describes how visible light passes through a material. A transparent material allows visible light to pass through it. Some of the light may be absorbed, but it is possible to see objects through the material. Familiar examples of transparent materials are air, water, some plastics and clear glass. Translucent materials allow some light …
Light does not pass through what kind of materials? | Socratic
2017年9月11日 · 1 Answer. Light does not pass through opaque materials. The other 2 characteristics related to light passing through materials are translucent (light gets thru but distortion prevents seeing anything thru it) and transparent (lights gets thru without distortion, allowing vision). Light does not pass through opaque materials.
Is a mirror's surface transparent, translucent, or opaque ... - Socratic
2018年1月20日 · Same is the case with mirror. Thus it is an opaque surface. Mirrors have an opaque surface. In an opaque surface,you cannot see behind it. Same is the case with mirror.
What is the index of refraction? - Socratic
2014年4月14日 · The index of refraction of a material is a ratio that compares the speed of light in a vacuum (c = 3.00x108 m s) to the speed of light in that particular medium. It can be calculated, if one knows the speed of light in that medium, using the formula. As the index of refraction increases, the amount that the material bends the light increases.
Properties of ionic, covalent, and metallic compounds
Here is a short list of main properties: They form crystals. Ionic compounds form crystal lattices rather than amorphous solids. They have higher enthalpies of fusion and vaporization than molecular compounds. They are hard. They are brittle. They have high melting points and also high boiling points. They conduct electricity but only when they ...
Separating Mixtures - Chemistry - Socratic
Mixtures that we can see all the different kinds of materials are called heterogeneous mixtures. Tossed salad, gravel, mixed nuts, beach sand, nachos, mud puddles, fog, and Italian salad dressing are all mixtures. If you want to separate them, you can physically take them apart piece by piece. Here is an example of a heterogeneous mixture.
Is tracing paper a transparent object or translucent object?
2018年3月5日 · Explanation: Tracing paper is a translucent object because you can only partially see through it as light passes through it partially. A similar substitute of tracing paper that is a transparent medium would be clear plastic sheet. Translucent Tracing paper is a translucent object because you can only partially see through it as light passes ...
Physical and Chemical Changes - Chemistry - Socratic
Acting upon matter can cause it to change, but it is useful to separate these changes into two different categories: physical and chemical. A chemical change describes a process that changes one material into another. Burning wood causes it to turn into ash, a different material. A physical change is simply changing the shape or state, such as cutting a piece of wood into two pieces.
Properties of Solids, Liquids, and Gases - Chemistry - Socratic
All liquids show the following characteristics: Liquids are almost incompressible. In liquids molecules are pretty close to each other. The molecules does not have lot of space between them. The molecules can not squeezed closer to one another. Liquids have fixed volume but no fixed shape.They have fixed volume but they do not have fixed or ...
A box with a square base and open top must have a volume of
2015年4月15日 · The Volume of a box with a square base x by x cm and height h cm is V=x^2h The amount of material used is directly proportional to the surface area, so we will minimize the amount of material by minimizing the surface area. The surface area of the box described is A=x^2 +4xh We need A as a function of x alone, so we'll use the fact that V=x^2h = 32,000 …
