fields of fiber optics‚ lasers‚ and integrated optics‚ the term radiation pattern‚ or near-field radiation pattern‚ may also be used as a synonym for the near-field pattern or Fresnel pattern.[4] This refers to the positional dependence of the electromagnetic field in the near-field‚ or Fresnel region of the source. The near-field pattern is most commonly defined over a plane placed in front of the source‚ or over a cylindrical or spherical surface enclosing it.[1][4] The far-field pattern of an antenna

Many studies have been performed to try to prove that cell phone electromagnetic radiation‚ in the form of radiofrequency‚ can indeed damage DNA. In the document “Cell Phones and Cancer Risk‚” from the National Cancer Institute‚ it states that: “The results of these studies have generally not provided clear evidence of a

The sun’s light waves‚ also known as radiation or electromagnetic energy‚ are measured and organized into the electromagnetic spectrum. Waves on the electromagnetic spectrum are measured in nanometers (nm); the shorter a wave is‚ the more energy it possesses‚ and the longer the wave the less energy it possesses (Wiles‚ 2013). The sun’s light waves are absorbed

The speed of light is 3.0X108 m/s. • Luminous objects became visible because of the light they emitted while illuminated objects do not emit light but they are capable of reflecting

Sound and music are parts of our everyday sensory experience. Just as humans have eyes for the detection of light and color‚ so we are equipped with ears for the detection of sound. We seldom take the time to ponder the characteristics and behaviors of sound and the mechanisms by which sounds are produced‚ propagated‚ and detected. The basis for an understanding of sound‚ music and hearing is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium

Introduction When light interacts with matter‚ the structures and properties of atoms and molecules are determined. This technique is spectroscopy where it absorbs‚ emits‚ or scatters electromagnetic radiation. Electromagnetic radiation has particle-like properties having photons and quantum and

different ways to study stars‚ planets and moons in the universe; but the most useful would have to be radio astronomy. Despite this‚ there are some who do argue that optical astronomy is the more useful of the two. Radio waves are a form of electromagnetic radiation and are given and received by many devices we use today‚ such as the radio‚ mobile phone or TV‚ but they have also been detected in space. Radio waves have long wavelengths at a low frequency‚ carrying less energy. Radio

A photon is a ‘packet’ of quantum of electromagnetic waves. An electromagnetic wave consists of an electric wave and a magnetic wave which travel together and vibrate: *at right angles to each other and to the direction in which they are travelling. *in phase with each other. As you can see the two waves reach
