Did you know that ...? Is the human ear sensitive to air vibrations with frequencies between 20 Hz and 20 kHz, with a maximum auditory sensitivity around 3500 Hz? This interval depends a lot on the amplitude of the vibration and on the age and state of health of the individual. Thus, sound can be defined as the sensation produced in the ear by vibrations or as the energy produced by vibrations or changes in pressure.
What does the book present?
How does a phone work? Who invented the radio and how are its signals sent? If you want to know about all these things and much more, here is a necessary book for basic knowledge, with a less technical content, helping a lot to unravel some 'mysteries'.
There are also detailed plans for many projects - including simple radio receivers, microphones, amplifiers and information on how to send and receive telegraphic radio signals.
All projects can be designed in your own workshop and are presented in a clear, interesting way, which arouses the curiosity of the young scientist.
