colors on a spectrum than we could see. Because light is a wave oscillates electric and magnetic fields it can be identified as an electromagnetic wave. Electromagnetic waves vary depending on frequency and the wavelength. There is a wide range of wavelengths in the electromagnetic spectrum which its frequency ranges from 1020 Hz to 106Hz. Transverse waves is an Electromagnetic wave theory of oscillating electric and magnetic field. These fields are put on a scale moving perpendicular to the…

sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the other hand, sound wave requires physical medium…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…

What is refraction Refraction is the bending of light when it passes from one medium to another, as light travels through one medium such as air it will travel at a certain velocity but once it enters another medium such as glass it will change direction due to the increase in density of the medium which slows down the velocity of the light. The amount that the light bends as it travels through a medium depends on how drastic the difference in optical density is. For example if light were to…

Figure 21: Dependence of the penetration depth on dwell times for different indentation peak loads Figure 22: Dependence of the penetration depth on dwell time for different indentation peak loads in ln-ln plot 5.4 HV vs. penetration depth Figure 23 shows the dependence of the Vickers hardness on the indenter penetration depth for 100mN to 1000mN and 10 s to 60 s dwelling time. The highest hardness value is 15.6GPa. As the indenter penetration depth increases, the hardness value decreases.…

An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…

Fresnel Equations The intensity of reflection in between two different medium of propagation can be calculated by using Fresnel’s equation. Light can either be s-polarized, p-polarized or unpolarized. The light radiated by the sun is an unpolarized light. In order to calculate the total reflection of an unpolarized light, we must first solve the reflected light using the Fresnel equation for s and p polarized reflection. For simplification purpose, the derivation of Fresnel’s equation will be…

3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

the order of red, orange, yellow, green, blue, indigo, and violet, shortly referred to as ROYGBIV, from top to bottom and appear in this order because of their wavelengths, which vary from 400 nm (nanometre or 10-9 m) to 700 nm as shown in the electromagnetic spectrum. In a primary rainbow, which is when light reflects a single time within the water droplet, red appears at the top of the rainbow because it has the longest wavelength, which is 700 nm, and is refracted the least when white light…

The Kinect V2 is composed of a time-of-flight continues-wave camera with a resolution of 512*424 pixels (width*height), an RGB camera with a resolution of 1920*1080 pixels (width*height), an array of 4 microphones and some electronics for signal elaboration. The camera is able to acquire images at a maximum frequency of 30 Hz. Sending out invisible structures pulses into the scene whilst measuring the individual traveling time of each point in the pulse (See figure 3.1, page 16). The operating…
