18/30 = 0.6 Hz.
5 wavs in 2 seconds = 2.5 waves per second = 2.5 Hz
20 waves per minute. (or 1 every 3 seconds)
Frequency
The speed of a wave = (wavelength) times (frequency) = (10) x (1/2) = 5 meters per second.
The frequency is 6 per 2 seconds = 3 Hz. The period is the reciprocal of the frequency = 1/3 second.
5 wavs in 2 seconds = 2.5 waves per second = 2.5 Hz
"frequency"
The frequency of a wave is the amount of cycles that pass the observer in any time.
20 waves per minute. (or 1 every 3 seconds)
Frequency
6.6666666...... Hz
This is known as the frequency of the wave.
Frequency
The number of waves that pass a point in 1 second
The number of waves that pass a fixed point in a fixed amount of time is known as the "frequency".=====is called the Frequency of the waves (located on page 10 of the Penn Foster - Sound Study Guide)=====The number of waves that pass a given point per second is measured in units of Hertz (Hz). Hertz is a unit for cycles per second.The number of cycles that a wave completes in 'S' seconds is 'S' times its 'frequency'.
Frequency.
Frequency is the number of waves that pass a fixed place in a given amount of time.
