Calculating Frequency

Step-By-Step:

1. Count how many divisions one wave occupies.

2. Find the the timebase, which is the amount of time it takes the spot to move one more division.

3. Multiply the answers from step one with the product of step two, to find the time one wave will take.

4. To find the frequency, you now need to divide your answer from step one the time taken for one wave to travel.
