Refractive index Transmittance Reflectivity
1. ** Refractive Index ** - The index of refraction reflected the ability of the lens to reflect light. When light entered different media, the angle would change, and this phenomenon was represented by the index of refraction. When the light beam is close to normal incidence (the angle of incidence is approximately equal to zero), the calculation formula for the reflection rate is related to the true index of refraction of the two media (that is, the index of refraction relative to vacuum). In different optical phenomena and calculations, such as the study of thin films on thick surfaces, as well as the measurement of the thickness and refraction index of samples in the low absorption region, the refraction index was an important factor. For example, in the experiment of measuring the thickness and the refraction index of the sample in the low absorption region, in order to accurately measure the surface toughness and the refraction index, it was necessary to fit the relevant curve. 2. ** Transmittance ** - The transmission is related to the reflection, and the sum of the two is 1 (Ras+Tas = 1). In some studies, such as the study of the optical properties of samples in the low absorption region, it would involve extracting the optical properties of the film from the transmission data, but this method may lack accuracy. There may be difficulties in fitting the transmission data. For example, when measuring the thickness and refraction index of the sample in the low absorption region based on the classical transmission line method (TLM) principle and method, it is difficult to find the fitting parameters of each function and lack accuracy when fitting the cos (?) based on the transmission. 3. ** Reflectivity ** - The percentage of the radiation energy reflected by an object to the total radiation energy is called the reflection rate. The range was that the reflection rate was less than or equal to 1. Different objects had different reflective rates, mainly depending on the nature of the object itself (surface condition), as well as the wave length and angle of the incident electromagnetic wave. Among the common types, the planet's refraction was an important physical quantity that described the physical properties of the planet's surface. For example, Venus's refraction was 76%, Mercury's was 10%, Earth's refraction was roughly between 35% and 43%, seawater's refraction (refraction) for short-wave radiation was 5%, and white ice and snow's refraction was 30 - 80%. Opaque media such as mirrors had a reflection rate of 100%, while non-mirrors were related to factors such as color, temperature, and light attributes. The magnitude of the reflective rate of a transparent medium was related to the angle of incidence of light. The larger the angle of incidence, the greater the reflective rate. For example, when light entered a light sparse medium from a light dense medium, when the angle of incidence reached a critical angle, the phenomenon of total reflection would occur. When the angle of incidence was less than the critical angle, it would be partial reflection. In the calculation of some optical phenomena, there were also calculation formulas related to the reflection, such as Vs =(sin(Theta1-Theta2)/sin(Theta1 + Theta2))^2 (Rp=(tan(Theta1-Theta2)/tan(Theta1 + Theta2))^2), etc. In some optical experiments and theoretical research, the reflection data could also be used to extract the optical characteristics of the film.

Refractive index and reflective index of matter
There was a close relationship between the index of refraction and the index of reflection. The relationship between the two can be seen from the formula, R =<<frac>{n1-n2}{n1 + n2}>>(the Fresnel formula, where <R> represents the reflection index, and <n1> and <n2> represent the refraction index of light when it enters medium 2 from medium 1). In addition, according to Snell's Law: <</><<</></><</>>), the relationship between the refraction index and the When light enters another medium vertically from one medium (that is, the angle of incidence is <alpha>=<alpha>= 0>), the greater the difference in the index of refraction between the two media, the greater the reflection. For example, when light enters a solid from a vacuum or air (the index of refraction is close to 1), the higher the index of refraction of the solid, the higher the reflection. The higher the index of refraction, the higher the reflection, and the stronger the luster. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Tile Reflectivity Reduces
The reflection of ceramic tiles is affected by many factors. The following are some of the factors that may reduce the reflection of ceramic tiles: - ** Tile Type **: Judging from the "skin" of the tiles, namely the glossiness, the glossiness of the mat tiles is lower, and its reflection rate is lower than that of the bright tiles. For example, bright bricks were high-gloss tiles, which had extremely high reflection under natural light and light, while dull bricks did not have such high reflective ability. - ** Tile Color **: Dark colored tiles have a relatively low reflective rate. For example, dark gray tiles have a relatively low reflective rate, while light gray tiles have a relatively high reflective rate. - ** Special Craftsmanship **: For example, the Cezanne Impression 36° Skin Brick has a reflection rate of less than 60%. It is achieved through special research and development technology. Through the introduction of advanced equipment and technological innovation, other functions such as wear resistance reaching level 4 and hardness reaching level 6 - 7 are met, while the reflection rate is reduced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflectivity of Ground Surface in Near-infrared Wavelands
Different objects had very different near infrared reflections. Plants have unique characteristics in the near-infrared band. There is a steep slope of reflection between 0.8 - 1.0um and a peak near 1.1um. The soil did not have obvious peaks and valleys. The finer the soil, the higher the reflection rate. The higher the organic matter content and the higher the water content, the lower the reflection rate. Water had a strong absorption in the near-infrared band, and the reflection rate was almost zero. The reflection rate of pure water was zero, and the reflection rate of clear water with chloride-containing water peaked in the green light band. The reflection rate of turbid water and silt water was higher than that of pure water, and the peak appeared in the yellow band. The spectral curves of snow, wheat, wet land, deserts, and other objects were different, and the near infrared reflection rate was also different. Snow, wheat (normal wheat and infested wheat had different spectral curves), and so on all had different near infrared reflection characteristics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
