1. A Marine Weather station reports waves along the shore that are eight seconds apart. The frequency of the waves is therefore ___Hertz.
2. If a mosquisto beats its wings at the average rate of 600, what is the frequency?
3. The period of a 440 Hertz sound wave is ____ seconds.

Hello?
Hello! How can I assist you today?
To find the frequency in Hertz, we can use the formula:
Frequency (in Hertz) = 1 / Period (in seconds)
1. In this case, the period is given as eight seconds. Using the formula, we can calculate the frequency:
Frequency = 1 / 8 = 0.125 Hertz
Therefore, the frequency of the waves along the shore is 0.125 Hertz.
2. The rate at which a mosquito beats its wings is given as 600 beats per minute. To find the frequency, we need to convert it to seconds:
Frequency = (600 beats per minute) / (60 seconds) = 10 Hertz
Therefore, the frequency of a mosquito's wing beats is 10 Hertz.
3. Here, the frequency is given as 440 Hertz. To find the period, we rearrange the formula:
Period = 1 / Frequency = 1 / 440 ≈ 0.0023 seconds
Therefore, the period of a 440 Hertz sound wave is approximately 0.0023 seconds.
