Antonio 3. A certain light source is emitting radiation with a frequency of 5.55x1015 Hz. a) What is the wavelength of the emitted photons? b) In what part of the electromagnetic spectrum are the emitted photons? 4. Suppose a dark hydrogen line in a star’s spectrum is produced at a wavelength of 6563 A‚ BUT this line has a MEASURED wavelength of 6560 A. (a) Would this star be moving toward us or away? (b) How fast would it be moving along our line

Introduction This lab will introduce you to wireless spectrum analysis and supports this week’s TCO. TCO 7: Given a situation requiring a wireless network solution‚ propose an appropriate design for a wireless network using radio frequency based methods. Background Wireless signals are invisible to the human eye. To see these signals‚ a tool such as a spectrum analyzer is required. In this lab‚ you will learn how to use a common spectrum analyzer‚ as you would in your career‚ to locate potential

frequency (RF) Electromagnetic energy (EME) radiated from Mobile telephone base stations were conducted in following manner. The base stations antenna on these sites are the more common panel antenna‚ which divide the area around the base station into three sectors (i.e. α = 1200‚ β = 1200‚ and γ = 1200). With this arrangement of the three Antennas all the region around the base stations are covered. All measurements were made with an Agilent Technologies model E4407B ESA-E series spectrum analyzer.

Autism‚ also known as Autism Spectrum Disorder (ASD) is unique as there are multiple factors causing the disorder. According to The National Autism Society of Malaysia (NASOM)‚ 1 out of 68 newborns in Malaysia is estimated to have autism. Autism is not the same as being shy or do not know what to say to others instead people with ASD are unable to understand the basic social conventions that others take for granted such as making eye contact‚ holding a conversation‚ or recognising gestures (Autism

points on the crest of a wave. The direction of propagation of a wave is perpendicular to its wavefront. A transverse wave is a wave in which particles of the medium oscillate in the direction of the propagation of the waves. Water waves and electromagnetic waves are examples of this type of waves. A longitudinal wave is a wave which the particles of the medium oscillate in the direction parallel to the direction in which the wave moves Sound waves is the example of this type of waves. What is

and chromatic aberration in lenses. In opaque media‚ the refractive index is a complex number: while the real part describes refraction‚ the imaginary part accounts for absorption. The concept of refractive index is widely used within the full electromagnetic spectrum‚ from x-rays to radio waves. It can also be used with wave phenomena other than light (e.g.‚ sound). In this case the speed of sound is used instead of that of light and a reference medium other than vacuum must be chosen.[2] Contents [hide]

an unknown solution. 6. Convert a molar concentration to a mass percent value. INTRODUCTION Electromagnetic radiation‚ of which ultraviolet and visible light are but two examples‚ has properties of both waves and particles. When light acts as a particle‚ called a photon‚ each light particle possesses a discrete amount of energy called a quantum. When a molecule is exposed to electromagnetic energy it can absorb a photon‚ increasing its energy by an amount equal to the energy of the photon
