T4B: Relationship between frequency and wavelength, identification of bands, names of frequency ranges, types of waves
T4B01:
What is the name for the distance a radio wave travels during one complete cycle?
Wavelength
Wave speed
Waveform
Wave spread
T4B02:
What term describes the number of times that an alternating current flows back and forth per second?
Frequency
Pulse rate
Speed
Wavelength
T4B03:
What does 60 hertz (Hz) mean?
60 cycles per second
6000 cycles per second
6000 meters per second
60 meters per second
T4B04:
Electromagnetic waves that oscillate more than 20,000 times per second as they travel through space are generally referred to as what?
Radio waves
Gravity waves
Sound waves
Gamma radiation
T4B05:
How fast does a radio wave travel through space?
At the speed of light
At the speed of sound
Its speed is inversely proportional to its wavelength
Its speed increases as the frequency increases
T4B06:
How does the wavelength of a radio wave relate to its frequency?
The wavelength gets shorter as the frequency increases
The wavelength gets longer as the frequency increases
There is no relationship between wavelength and frequency
The wavelength depends on the bandwidth of the signal
T4B07:
What is the formula for converting frequency to wavelength in meters?
Wavelength in meters equals 300 divided by frequency in megahertz
Wavelength in meters equals frequency in Hertz multiplied by 300
Wavelength in meters equals frequency in Hertz divided by 300
Wavelength in meters equals frequency in megahertz divided by 300
T4B08:
What are sound waves in the range between 300 and 3000 Hertz called?
Voice frequencies
Test signals
Ultrasonic waves
Radio frequencies
T4B09:
What property of a radio wave is often used to identify the different bands amateur radio operators use?
The physical length of the wave
The magnetic intensity of the wave
The time it takes for the wave to travel one mile
The voltage standing wave ratio of the wave
