Answer:
n = 24 waves
Explanation:
As, the sound is produced with a steady pitch. Therefore, it means that there is no change in the pitch with respect to time. Hence, we can work with the following formula for frequency:
υ = n/t
where,
υ = frequency of sound wave = 6 waves/s
n = no. of waves = ?
t = time interval = 4 s
Therefore, using these values in the equation we get:
6 waves/s = n/4 s
n = (6 waves/s)(4 s)
n = 24 waves
