What material reflects heat the best? What determines the color of a photon? What is the frequency of blue light that has a wavelength of 444 nm ? What colors are absorbed when white light hits a red apple? How does a prism reflect colors?
As far as I am concerned, we ought to recycle textbooks as a way of protecting environment. For one thing, recycling textbooks can not only save natural resources such as wood, but also reduce the waste of material. For another, the notes on the textbooks, made by the graduated students ...

What material reflects heat the best? What material reflects sound waves the best? All objects emit what kind of radiation? What discovery demonstrated that atoms are mostly empty space? What are the particles that make up matter? What did Isaac Newton discover about moving ...
Thermal resistance is resistance that heat encounters in the flow path, which reflects heat transfer capacity between medium. It indicates temperature rising degrees caused by 1W heat quantity. Thermal resistance R is calculated as below: Thermal resistance is in proportion to material’s thickness, ...
In hot climates, however, linen is still used to produce everyday clothing in large quantities. People living near equatorial regions can benefit from linen’s high moisture-wicking but low moisture-retaining profile, and the natural white color of this fabric inherently reflects heat-inducing solar...
✗ Rock mulch absorbs and reflects heat ✗ Plastic sheeting prevents the flow of air and water ✗ Landscape fabric can suffocate worms Types of organic mulch Because organic mulches were once alive, they slowly decompose on your lawn over time. The decomposition of organic material gives your...
Art, on the other hand, is subjective; it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly “political” artist. In his well known painting The Third of May, 1808, he criticized the Spanish government for its misuse of power over people. ...
Material Integrity:Prolonged exposure to microwave heat can lead to the breakdown or warping of materials. This is especially true for certain plastics and ceramics. Reheating minimizes the risk by limiting heat exposure. Health Considerations:Some materials may release harmful chemicals when subjected to...
The temperature of an object is the measure of its 'hotness' or 'coldness' and reflects the thermal energy present in that object. Heat is a form of energy. When heat is absorbed by an object, its temperature increases. On the other hand, if heat is removed from an ob...
