testing

• What are radiowaves characterized by?

  Longest wavelengths and lowest frequency
• What is the purpose of an oscilloscope?

  To visualize electrical signals over time
• How does an oscilloscope help in determining the frequency of a wave?

  It displays the waveform, allowing frequency measurement
• What is required to detect a generated radio wave?

  Specific detection equipment
• What does 'a.c.' stand for?

  Alternating current
• How does the frequency of a.c. relate to the source?

  The frequency is the same as the source frequency
• What is necessary to generate a radio wave?

  Matching frequency with the source
• What is the relationship between the frequency of a.c. and the radio wave?

  They must match to generate the wave
