Come and see us at Czech European Researchers' Night! All physics departments invite you to their exhibition stands.

Department of Physical Electronics

  • Experimental workshop on the topic "Sight and hearing" - building 6, lecture room F2 - Our colleagues from the section Didactics of Physics prepared several experiments that will demonstrate the operation limitation of human sight. You will find out how far the sensitivity of our eye reaches in the red and blue area, the temporal and spatial resolution of your vision, or if you can perceive the polarization of light. Anyone who has no problem staying in the dark for half an hour can measure how many photons their eye needs to produce a light perception. We will also test your hearing. You will find out, for example, the lowest and highest tone you can still hear, the smallest frequency interval you can still distinguish, and how you perceive the intensity of sound. You will test how the music would sound at very (non-musically) high notes.
  • Why do people see only visible light? - building 6, lecture room F1 - lecture starts at 7:00 PM and 8:30 PM - Assoc. Prof. Zdeněk Bochníček will present an intriguing lecture on the limitation of human eyesight only to visible light. Humankind has long known that visible light is only a narrow part of a wide electromagnetic spectrum. But why is that? Why has evolution chosen only this part of the electromagnetic spectrum to be the visible one? Was it mere coincidence, or are there physical reasons for it? In this lecture, Assoc. Prof. Zdeněk Bochníček will discuss possible physical reasons with the help of demonstrative physical experiments.
  • Demonstration of experiments applicable in the industry - courtyard in front of building 7 - Roofed outdoor stands will await you in front of building No.7. And what to look for? Our colleagues Zlata Kelar Tučeková, Jakub Kelar, and students Roman Přibyl and Lucia Švandová will present the science and research at DPE through practical examples and demonstrations. You will find various physics applications, including different plasma sources. You can enjoy the plasma generated by those plasma sources through your senses, not only with your eyes, but you can touch the plasma directly! The exposition will be in Czech and English, and you will have an opportunity to win small prizes.
