AN OCEAN WAVE TRAVELS 18.8 METERS IN 5.1 SECONDS. THE DISTANCE BETWEEN THE 2 NEAREST WAVE CREST IS 4.1 METER. WHAT IS THE FREQUENCY?
freq=speed/wavelength=18.8/(5.1*4.1) = ?
To calculate the frequency of an ocean wave, we need to use the formula:
Frequency = 1 / Period
To find the period of the wave, we need to use the formula:
Period = Time / Number of Waves
First, let's find the number of waves:
Number of Waves = Distance Traveled / Distance between Crests
Number of Waves = 18.8 meters / 4.1 meters
Number of Waves ≈ 4.585 waves
Now, let's calculate the period:
Period = Time / Number of Waves
Period = 5.1 seconds / 4.585 waves
Period ≈ 1.113 seconds per wave
Finally, to find the frequency, we can use the formula:
Frequency = 1 / Period
Frequency = 1 / 1.113 seconds per wave
Frequency ≈ 0.898 Hz
Therefore, the frequency of the ocean wave is approximately 0.898 Hz.
