Questions and CORRECT Answers
Frequency - CORRECT ANSWER- describes the NUMBER OF TIMES per second that an
alternating current makes a complete cycle.
Symbol for Frequency - CORRECT ANSWER- f
Frequency - Unit of Measurement - CORRECT ANSWER- Hertz
Abbreviation for Hertz - CORRECT ANSWER- Hz
Wavelength - CORRECT ANSWER- is the name for the DISTANCE a radio wave travels
during one complete cycle.
Symbol for Wavelength - CORRECT ANSWER- λ
Wavelength - Unit of Measurement - CORRECT ANSWER- Meters
Abbreviation for Meters - CORRECT ANSWER- m
What is the formula for converting frequency to approximate wavelength in meters? -
CORRECT ANSWER- Wavelength in meters equals 300 divided by frequency in megahertz.
| λ in meters = 300 / f in MHz | [Wavelength in Meters = 300 / Frequency in MegaHertz]

Voltage - Unit of Measurement - CORRECT ANSWER- Volts
Abbreviation for Volts - CORRECT ANSWER- V
Voltmeter - CORRECT ANSWER- the instrument would you use to measure electric
potential or ELECTROMOTIVE FORCE.
Resistance - CORRECT ANSWER- is how much a material opposes the flow of electrons
through it.
Symbol for Resistance - CORRECT ANSWER- R
Resistance - Unit of Measurement - CORRECT ANSWER- Ohms
, Abbreviation for Ohms - CORRECT ANSWER- Ω
