Measuring Unknown Strobe Rate
Name: Reade W.
How can I measure the flash rate of a strobe light at its full pulse rate,
because the box does not say the exact flash rate per second and that is what i need for
my current experiment dealing with projectile motion of a soccer ball, which we will be
recording on a video camera while with a strobe light, flashing to break up the motion...
so how can i find out my flash rate per second of my strobe light?
You can take an object and drop it along a scale while photographing it under the flash
The amount of fall is y = y initial +v initial * time + 0.5 g t^2
Since the first two terms are zero, you measure y off the image, and you know g, you can
solve for t.
