Electromagnetic pulse

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…

Scientists have the ability to determine the molarity and the contents of a substance by measuring the intensity of the light that is emitted through the solution. Scientists accomplish this by using the technique of spectroscopy; spectroscopy can be defined as the science affiliated with the spectra produced when matter interacts with light. Lab 7 investigation 19, “What Factors Affect the Intensity of Color?” expands on the process of spectroscopy, and its relation to the molarity of a…

temporal resolution of UEM by generation ~ 30 fs electron pulse (200 KeV) by the optical-gating approach using a visible laser pulse with the strength for probing the matter dynamics. Moreover, the…

All Colors of the Visible Spectrum Grow Salvia Splendens More Efficiently than Red or Green Light on Its Own By: Diego Prado, Morgan Miller, Cody Holland, and Jonathan Ruppel Introduction The hypothesis for lab 5 was that plants that do not receive red light will perform photosynthesis less efficiently than those exposed to light of all wavelengths. The findings for that lab were that the plant that received all colors grew the most. The experiment was done again, but this time the algae was…

Rosseland Radiation Model The Rosseland Model (Diffusion approximation model) is applicable when the medium is optically thick i.e. the optical thickness is much greater than 1 where a is the absorption coefficient of the medium, σ is the scattering coefficient of the medium and L is the average path length. The radiative heat flux is approximated as [3], (2.13) where qr is the radiative heat flux, Γ is the radiative diffusivity and G is the incident radiation. In contrast to the P-1 model…

Non – reciprocal device states that, the devices which are having the properties that the forward characteristics are not equal to the reverse characteristics (i.e. S12 ≠ S21). So, same antenna can be used for Transmission and Reception of Electromagnetic Waves. Antenna is a passive device, it does not amplify the signals, and it only directs the signal energy in a particular direction in reference with isotropic antenna. Antenna Beam width is the angular width measured at the half power points…

An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…

The term photoluminescence by definition can be refered to as a molecule or atom which absorbs electromagnetic energy and in turn, emits light.In quantum mechanics, it is where excitation to a higher energy state occurs, which then returns to a lower energy state, together with the emission of a photon. According to Seitz (2006) found in the Credo referencing database, “Photoluminescence excitation spectra are determined by measuring emission intensity at a fixed wavelength while varying the…

Acoustics is the branch of physics concerned with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules…

Introduction A wave is a repeating disturbance or movement that transfers energy through matter or space. Waves are caused by vibrations. There are two types of waves, transverse, and longitudinal waves. The moving particles in transverse waves travel at right angles to the direction of transverse. Some examples of transverse waves are light waves and radio waves. A longitudinal wave is also known as a compression wave. The moving particles move back and forth in the same direction as the wave.…
