Electromagnetic radiation

Please 1) describe what is meant by the terms short-wave and long-wave energy, 2) namea specific type of electromagnetic energy for each type, and 3) correctly identify which is associated with the energy emitted from the Sun and the Earth. Short-wave electromagnetic energy has a short wavelength and high energy, while long-wave electromagnetic energy has a long wavelength and low energy. The wavelendth refers to the sine function that describes the eneregy's osicalation through time. Higher…

2.5. Color Temperature Color temperature is a characteristic of visible light that has important applications in a variety of fields such as lighting, photography, videography, astrophysics, manufacturing and publishing. In generally the hues of light generated are either warm (yellowish) or cool (bluish) and measured in degrees of Kelvin (K) 2.5.1. Technical Definition The color temperature of a light source is defined as the color temperature of a black body radiator that radiates light of…

definition: • They are empirical mathematical formulation for the characterization of radio wave propagation as a function of frequency, distance and other conditions. • These models predict the path loss (i.e. the reduction in power density of an electromagnetic wave as it propagates through space or underground) of a transmitter and also the effective coverage area of transmitter. We know that when a signal travels from a wireless channel, it undergoes various types of Propagation Effects…

What is the photon detection efficiency (PDE) of a SiPM? Photon detection efficiency (PDE) refers to the probability that a photon arriving on the SiPM surface is detected, an initiates the process of current pulse generation. PDE is a function of the overvoltage ΔV across the terminals of the APD and wavelength λ of the incident photon. Photon detection efficiency is one of the most important characteristics of a SiPM. PDE is the product of three factors :- Geometrical fill factor (FF), Quantum…

A wave is a disturbance of energy. Sound and light are both disturbances in energy, and they both travel in the forms of waves. While sound travels in a longitudinal wave, light travels through a transverse wave. From a perspective of a human, sound and light on earth is very different compared to sound and light in space. These waves have differences in speed, form, shape, and other properties. Despite many of the differences, sound and light are very similar to each other. Light is a…

Copper is the most common target material used. When these electrons are interacted with the target and characteristic X-rays are produced. This X-ray spectrum consists of several components. These X-rays are then collimated to get Kα1 and Kα2 radiations then directed towards the sample. When Bragg’s law is satisfied, the constructive interference occurs and its corresponding intensity peak is observed. In the θ-2θ mode spectrometer, X-ray source remains in fixed position and the detector fixed…

3.1. GENERAL SPECIFICATIONS The project is an Arduino- based project and is based concerning radio frequency according to ship then get hold of the data. The RF transmitter and grantee each work at a 433 MHz to send then get hold of data. We will be adding the use of an ultrasonic, which measures the scale in conformity with an object, through the usage of echo waves. An LCD show choice is aged to show the statistics managed with the aid of the Arduino. The dictation is computerized therefore…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

Do you think you could live in a world without your phone or computer? What about a world without electrical power at all? Well if an Electromagnetic Pulse, also known as an EMP were to occur, it would change the technology world forever. Such threats are often dismissed as unlikely or a relic from the Cold War. They are not. Solar storms are not infrequent, making it only a matter of time until one impacts our critical infrastructure. And unlike natural phenomena, there is no reliable…

1. Doppler radar systems provide information about the movement and position of targets. They work by sending a beam of electromagnetic waves at a specific frequency, at a moving object. When a microwave bounces off the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location. 2. Polarized sunglasses block reflected light (glare). Since polarized light waves…
