3. Were oxygen present it would combine with the hot tungsten.

4. The pentode, so named because it contains five electrodes, was developed to provide a means to eliminate or minimise secondary emission, an emission of electrons.

5. Since electrons are negative charges, they fly to the plate only when the plate is positive.

6. When alternating voltage is applied to the plate, it becomes alternately positive and negative so that plate current flows only during that half of the time when the plate is positive, and only in one direction.

7. The process by which the signal being transmitted is reproduced from the radio-frequency currents present at the receiver is called detection, or sometimes demodulation.

8. The delay may amount to the time of several cycles although, of course, the output frequency is the same as the input frequency.

9. One way to do this is to vary the amplitude of the radiated wave in accordance with the intelligence which is to be transmitted.

10. That the radio is the fastest and most reliable way to detect artificial satellites is well known to everybody.
