Wavelength
Answer 40MHz = 10mIf you measure the distance between two identical points
on a wave
you are measuring the
wavelength.
If you increase the frequency of a wave you
have to 'squash' it together
to get more cycles into a second so the
wavelength decreases.
If you decrease the frequency you increase
the wavelength as you have
'stretched' the wave.
You can use this graph to convert between wavelength and frequency. You
will have a copy of this graph in the test.
If I am transmitting on 40MHz, what wavelength am I using?
1. Mark 40MHz on the horizontal axis of the graph
2. Draw a vertical line upwards until you hit the graph
When converting from
wavelength to frequency turn the graph so that wavelength is on the horizontal
axis
then follow the steps as above.
3. Draw a horizontal
line until you hit the vertical axis
Answer 40MHz = 10m
4. Read off the
number from the vertical axis
