∙ 13y agoFrequency is measured in Hertz (Hz), which is the number of wavelengths that pass in one second. Since one wavelength is passing every eight seconds, the frequency is 1/8 Hz.
18/30 = 0.6 Hz.
5 wavs in 2 seconds = 2.5 waves per second = 2.5 Hz
Frequency is the amount of cycles within a given amount of time. It is usually described in units of 1/s, where s is seconds. If the wave is traveling, count the amount of peaks that pass by a certain reference point within a measured amount of time. Take the amount of peaks that have passed, and divide that quantity by the amount of time that has passed. If the wave is not traveling (ie, a spring motion), count the amount of cycles within a measured amount of time. Then, as before, divide this quantity by the amount of time that has passed.
20 waves per minute. (or 1 every 3 seconds)
The number of wave peaks that pass a point in one second is called the frequency of the wave. It is measured in hertz (Hz).
The frequency is 2 Hz. This is because frequency is calculated by dividing the number of waves that pass a point by the time it takes for them to pass. In this case, 20 waves pass a point in 10 seconds, so the frequency is 20 waves / 10 seconds = 2 Hz.
The Period
The period of a wave is the time it takes for one complete cycle to pass a point. It is the reciprocal of the frequency. Therefore, a wave with a frequency of 20 Hz would have a period of 0.05 seconds (1/20 = 0.05). The wavelength of 2.0 m is unrelated to the period in this case.
The frequency of the wave is 0.5 Hz. This is calculated by dividing the number of crests (3) by the time it takes for them to pass (6 seconds).
The frequency of the wave is 3 Hz. This is calculated by dividing the number of waves (6) by the time it took for them to pass (2 seconds).
The frequency is 0.5 Hz. Since five waves pass in 10 seconds, you divide the number of waves by the time taken to find the frequency, which is five waves / 10 seconds = 0.5 Hz.
The period of a wave is the time it takes for one complete cycle to pass a fixed point. If 20 crests pass an observer in 4 seconds, then the period of the wave is the time it takes for one crest to pass, which is 4 seconds divided by 20, giving a period of 0.2 seconds.
Period = 1 / frequency
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).
The term for the amount of time it takes for one wave to pass by a given point is the "period." It is measured in seconds and is the reciprocal of the frequency of the wave.
The frequency of the waves is 0.5 Hz (10 waves / 20 seconds). The time period is 2 seconds (1 / 0.5 Hz). The wavelength of the waves would depend on the speed of the waves in the medium they are traveling through.
