POSTER: Electromagnetic Radiation Spectrum

Poster: Electromagnetic Radiation Spectrum Giga-, kilo- and micro- got your head swimming"

Want to know how long is a microwave wavelength" Interested in what is going on at different EM frequencies" This finely detailed poster relates all known ranges of EMR including gamma rays, X-rays, ultraviolet light, visible light, infrared, microwaves, radio waves (ULF, VLF, LF, MF, HF, long, short, HAM, VHF, UHF, SHF, EHF), cosmic microwave background radiation and brain waves, all organized by octaves. The audio frequency spectrum is also included. Reference to everyday items such as music, brainwaves, football fields and cellphones makes understanding EMR easier. Colorful descriptions are included for all ranges and properties of EMR including reflection, refraction, LASER, television, gravity waves, emission and absorption. There is also a handy chart of SI unit prefixes ranging from yocto to yotta (this is the "Giga, kilo, micro" part).

24" x 36" professionally printed posters on 100lb glossy paper suitable for framing. Great for home, office, or classroom.

by Thomas Kubala

Building on the foundation established in Electricity 1, this book goes on to explore alternating current principles and important concepts of inductive reactance, capacitive reactance, and impedance. Completely updated to the 2005 National Electrical Code, Electricity 2 acquaints newcomers to the field with various types of alternating current circuits, while developing a solid understanding of the concepts of power, power factor, and power factor correction. Sample problems and solutions at the end of each unit provide a direct route to understanding as readers apply key electrical principles in realistic troubleshooting situations.

  • enhancements to this edition include the latest terminology and a modernized art program featuring current photographs of electrical equipment
  • modern applications of power installations help prepare readers for work in the field
  • pragmatic troubleshooting methods are explored to help develop critical thinking skills
  • problems and solutions at the end of each unit help readers identify topics that require further review
