As previously stated, the velocity for all electromagnetic radiation is the same: 3 × 108 m/s. Class 11: Chemistry: Structure of Atom-I: Particle Nature of Electromagnetic Radiation: Planck’s quantum Theory Introduction Difference between Electromagnetic and Mechanical Energy The constant, h, which is named for Planck, is a mathematical value used to calculate photon energies based on frequency. In fact, energy and frequency of electromagnetic radiation are related mathematically. The radiographer should consider him or herself as a resource for the public and should be able to dispel any myths or misconceptions about medical imaging in general. Both ends of the electromagnetic spectrum are used in medical imaging. So does electromagnetic radiation consist of waves or particles? The sound from a speaker vibrates molecules of air adjacent to the speaker, which then pass the vibration to other nearby molecules until they reach the listener’s ear. The energy is measured in electron volts (eV). The Particle Nature of Light 1. All electromagnetic radiations have the same nature in that they are electric and magnetic disturbances traveling through space. Light, that is, visible, infrared and ultraviolet light, is usually described as though it is a wave. unit of wavelength is metre (m). The wave model of light cannot explain why heated objects emit only certain [frequencies] of light at a given temperature, or why some metals emit [electrons] when light of a specific frequency shines on them. Particulate Radiation visible light In general, it is the radiographer’s role to be familiar with the different types of radiation to which patients may be exposed and to be able to answer questions and educate patients. The key difference between wave and particle nature of light is that the wave nature of light states that light can behave as an electromagnetic wave, whereas the particle nature of light states that light consists of particles called photons. Differentiate between x-rays and gamma rays and the rest of the electromagnetic spectrum. He or she should also understand the nature of radiation well enough to safely use it for medical imaging purposes. The wavelengths of the electromagnetic spectrum range from 106 to10-16 meters (m) and the frequencies range from 102 to 1024 hertz (Hz). Related Key Ideas and Terms Notes Define frequency. The ranges of energy, frequency, and wavelength of the electromagnetic spectrum are continuous—that is, one constituent blends into the next (Figure 3-2). • Explain wave-particle duality as it applies to the electromagnetic spectrum. • Explain the relationship between energy and frequency of electromagnetic radiation. Unlike mechanical energy, which requires an object or matter to act through, electromagnetic energy can exist apart from matter and can travel through a vacuum. In this formula, E is energy, h is Planck’s constant (equal to 4.15 × 10-15 eV-sec), and f is the frequency of the photon. Define waves. He suggested that when electrically charged particles move with an acceleration alternating electrical and magnetic fields are produced and transmitted. One difference between the “ends” of the spectrum is that only high-energy radiation (x-rays and gamma rays) has the ability to ionize matter. The physicist Max Planck first described the direct proportionality between energy and frequency; that is, as the frequency increases, so does the energy. • Calculate the wavelength or frequency of electromagnetic radiation. One difference between the “ends” of the spectrum is that only high-energy radiation (x-rays and gamma rays) has the ability to ionize matter.
