Question 7

0.1 Hz Switches between Hi and Lo and pulsates but extremely slowly.

1 Hz Pulse constantly blinks about every second. Hi and Lo match the pulse while alternating

10 Hz The Pulse is blinking constantly but much faster. Hi and Lo alternate but much faster.

100 Hz Hi and Lo appear solid. Pulse is blinking rapidly.

1K Hz Hi and Lo appear solid. Pulse is blinking faster than 100 Hz.

10K Same as 1K Hz in appearance for Hi and Lo. Pulse is blinking faster

100K Hz Hi and Lo are solid. Pulse might be faster but it looks the same as 1K and 10K Hz
