Objects in the universe send out an enormous range of electromagnetic radiation. scientists call this range the electromagnetic spectrum, which they have divided into a number of categories. the spectrum is shown in figure 5.6, with some information about the waves in each part or band. figure 5.6 : radiation and earth’s atmosphere.
Paper 604 Electromagnetic Radiation Emr Figure 15.5 shows the section of the em spectrum that includes visible light. the frequencies corresponding to these wavelengths are 4.0 × 10 14 s −1 at the red end to 7.9 × 10 14 s −1 at the violet end. this is a very narrow range, considering that the em spectrum spans about 20 orders of magnitude. Understanding the properties of electromagnetic radiation and the electromagnetic spectrum is crucial for comprehending the fundamentals of x ray physics. x rays, as a form of ionizing radiation. Infrared radiation. the microwave and infrared regions of the electromagnetic spectrum overlap (figure 24.3.1). infrared radiation is generally produced by thermal motion and the vibration and rotation of atoms and molecules. electronic transitions in atoms and molecules can also produce infrared radiation. Electromagnetic radiation is a form of energy that is all around us and takes many forms, such as radio waves, microwaves, infrared, visible light, ultraviolet, x rays, and gamma rays. before 1873, electricity and magnetism were thought to be two different forces. however, in 1873, scottish physicist james maxwell developed his famous theory of.
