My Get Pushed partner for this week Smiffy @sm61ffy challenged me to "capture something fast moving , the choice of what you capture is up to you". I confess to seriously scratching my head over this because in recent challenges I have captured 'movement' and 'action' which are very similar to 'fast moving' - and the fastest moving thing where I live is a tractor or a cow!
Then I got to thinking - "What is the fastest moving thing?" and the answer is, of course, light which travels at 299,792 km per second. Now, since the word 'photograph' comes from the Greek meaning 'light-painting' - any and every photograph is a valid response to this challenge ;-)
I didn't think Smiffy would let me get away with that however, but electricity and radio waves also travel at the speed of light, so here is my answer to the challenge. A digital radio- frequency generator is producing a radio signal at a frequency of 10 MHz (you can see the frequency on the display) and that radio signal is being monitored on the oscilloscope. Voilà! Not just something fast moving but, rather, the fastest moving thing.
@sm61ffy Hello Smiffy - right at the deadline, here is my answer to your challenge to capture something fast moving. I'm sure this is far from what you might have been expecting but I hope you feel I have met the challenge.
@yrhenwr Thanks David, I haven't used this one for ages, but it has the traditional look - nowadays I use a Rigol 200 MHz digital 'scope and a Rigol 3 GHz Spectrum Analyser.
