6/30 = 1/5 Hz.
The frequency of the waves is 0.20 HZ.
18/30 = 0.6 Hz.
Multiply it by 60 to find how many seconds there are.
4 minutes 30 seconds
The wave frequency would be 0.2 Hz. (6 waves / 30 seconds = 0.2 Hz)
6/30 = 1/5 Hz.
-- If the ocean waves lap the shore every 15 seconds then their frequency is 1/15 Hz.-- If the waves come every 30 seconds then the frequency is 1/30 Hz.-- If the waves come every minute (60 seconds) then their frequency is 1/60 Hz....etc.In general, the frequency of ocean waves, and any other waves, is1/the number of seconds between consecutive waves
The frequency of the waves is 0.20 HZ.
The frequency of the waves would be 6 Hz. This is calculated by dividing the number of crests (30) by the time it took for them to pass (5 seconds).
18/30 = 0.6 Hz.
The frequency of the wave is 0.2 Hz. You can calculate it by dividing the number of waves (6) by the time it took for them to reach the shore (30 seconds).
There are 60 seconds in a minute, so to find the number of seconds in 30 minutes, you would multiply 60 by 30. This equals 1800 seconds. Therefore, there are 1800 seconds in 30 minutes.
Brain waves can be measured in units of frequency, typically in Hertz (Hz). The main types of brain waves are delta waves (0.5-4 Hz), theta waves (4-8 Hz), alpha waves (8-12 Hz), beta waves (12-30 Hz), and gamma waves (>30 Hz). These frequencies correspond to different states of consciousness and mental activity.
30 Hz is equal to 0.03 kHz. This conversion is done by dividing the frequency in Hertz by 1000.
1 wave / 8 seconds = 0.125 waves per second
Multiply it by 60 to find how many seconds there are.
