The main objective was to understand how energy travels through space and how we can interact with it\, whether to transmit information (sound) or to f ilter the visible spectrum (light).\n1. Building the Homemade Radio In the first stage\, we delved into the radio frequency spectrum. The challenge consisted of assembling a basic receiver circuit (likely a crystal radio o r simple LC circuit) capable of capturing signals without the\nneed for a complex power source.\n• The Process: We connected key components such a s the coil (inductance) and the capacitor to create a resonant circuit. I learned that the antenna length and tuning are critical to "catch" the spe cific frequency of a commercial\nstation.\n• The Result: It was fascinat ing to observe how\, by adjusting the circuit\, we were able to demodulate the signal and transform invisible electromagnetic waves into audible sou nd through the earpiece. This demonstrated the principle of resonance and the omnipresence of radio waves in our environment.\n2. Light Polarization Experiment The second part of the workshop focused on the visible spectru m\, specifically on the wave property of light. The instructor used polari zed panels or sheets to show us that light does not vibrate in a single di rection\, but in multiple planes.\n• The Observation: We were shown how a polarizing panel acts like a "grid" or "fence" that only allows light wa ves vibrating in a specific orientation to pass through.\n• The Angle Ph enomenon: The most revealing moment was when a second filter was superimpo sed\, or the angle of incidence was changed. By rotating the panel 90 degr ees relative to the polarized source (or relative to a second filter)\, th e light was blocked almost completely. I understood that by crossing the a xes of polarization\, the passage of the wave is prevented\, physically de monstrating that light behaves as a transverse wave.\n\nCholula\, Jalisco\ , Mexico LOCATION:Cholula\, Jalisco\, Mexico ORGANIZER:sarah_kohl@ieee.org SEQUENCE:24 SUMMARY:Radiometry Workshop URL;VALUE=URI:https://events.vtools.ieee.org/m/537148 X-ALT-DESC:Description: <br /><p>During this practical workshop\, we explor ed the nature and behavior of electromagnetic waves through two complement ary experiences: constructing a radio receiver and manipulating light thro ugh polarization.
