Physics Homework Help, Finding Frequency of a Wave

Posted on 2014-03-11 08:41:00 in Physics by HOLLY

1)An oscilloscope is set on a Time/Div setting up 50 µs. A sine wave output from a function generator has exactly three full cycles of the sine wave that fit in the 10 divisions on the screen. What is the frequency of the wave?



2)You found that when you set the function generator on 4000 H, the signal on the oscilloscope was not exactly 4000 Hz. Which value is truly more accurate, the one on the function generator knob or the one you get from the oscilloscope.
