AI Generated Solution

To find the frequency of the wave produced by the source, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Problem**: The source produces 40 crests and 40 troughs in 0.4 seconds. Since each oscillation consists of one crest and one trough, the total number of oscillations is equal to the number of crests (or troughs). 2. **Calculate the Total Number of Oscillations**: - Total number of oscillations = Number of crests = 40 (since each oscillation has one crest and one trough). ...
