The interactions between surfaces and light
The essay is aiming to explore he interactions between surfaces and light from several aspects, such as the reflections, transmission and so on. It uses a bathroom as an example to help people understand how the light and surfaces interact with each other. First of all, it tells readers some description about the bathroom. Following this, it makes some analysis about the relationships between the light and the layers. At last, it sums up the whole essay and gives readers the research outcomes.
There are lots of glasses in the bathroom. Besides, inside the bathroom, there is a big window, which can see the sun. Especially in summer, the sunshine will get inside the bathroom. Moreover, the bathroom is built by lots of ceramic tiles, which is also related with the lights.
Light reflection refers to the diffuse of the lights when they reach different kinds of surfaces of the materials (Donner & Jensen, 2005). For example, in the bathroom, when the lights hit the surface of the ceramic tiles, they will not be absorbed. Instead, they will be reflected in different kinds of directions. Thus, sometimes people will see the lots of lights in some architecture due to the light reflection. What is more, the light reflection can be found everywhere in people’s daily lives. Even the water, it can reflect the light. Therefore, in the bathroom, especially for the clean class, people may find the light dazzling as they lights are reflected to people’s eyes (Barron, 2004).
Light transmission is another type of interaction between light and surfaces. The lights may encounter the transparent and non-transparent materials when they travel (Apetz & Bruggen, 2003). For the transparent materials, the directions of the light may be not changed; otherwise, they may change their directions. If the light can get through the materials, it will be called light transmission. However, if they can not get through them, it is called the light reflection. The bulbs are the good examples. In the bathroom, people may find it is very bright of the bulbs, as the lights get through the transparent glass so that people find it bright. But the directions may have been changed when they get through the glasses.
Not all the light can be reflected or transmission. For the non transparent materials, they only can reflect certain kind of light and the other light will be absorbed, which is called light absorption (Bohren & Huffman, 2008). For example, the green one will reflect the green light and absorb the other light, thus, people can see its green color. But for the white materials and the black materials, they may be special. White materials can reflect all the light while the black one cannot reflect any light. When the black materials absorb all the lights, it will turn the light energy into the heat energy, which increases the temperature. Therefore, in the bathroom, most of people will use the white colors to decorate them, as it will not make the bathroom become too hot, especially in summer. What is more, the light refraction and light dispersion are also very important to the design of the bathroom. From the above, people can see that the light and the surface have a very close relationships. In other words, they can influence each other.
In a word, people should try their best to figure out the relationships between the light and the surfaces, which help people a lot in the designs of the architectures (Feynman, 2006). By knowing more about their interactions, people will be able to apply different colors of the lights in the actual situations. For example, as the black materials absorb all the lights, people may consider more when they use the black color materials, as it may increase the heats. What is more, people can learn more about the different use of the materials and the lights, which can be applied in the non-reflecting glasses and so on. In conclusion, exploring the interactions between the light and the surface does a great help to the innovation of the designs in the future. Thus, people can design whatever they like according to the light theories and the surfaces of the materials and so on.
