A wave has a period of 4 seconds find the frequency?
Time period = 1 / frequency. Frequency = 1 / time period.f = 1/4 = 0.25 Hz.
What is the frequency of a wave when one wave passes in 8 seconds?
Frequency 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.
If 18 waves pass the observer in 30 seconds the frequency isA?
18/30 = 0.6 Hz.
What is the frequency of a wave five waves pass in two seconds?
5 wavs in 2 seconds = 2.5 waves per second = 2.5 Hz
How do you find the frequency of a wave using a stopwatch?
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.
What is the frequency of a wave in terms of its peaks?
The frequency of a wave is the number of peaks that pass a certain point in a given amount of time.
What is the number of wave peaks that pass each second?
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).
When 20 waves pass a point in 10 seconds the frequency is?
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 time it takes one wavelength to pass a given point?
The Period
What is the period of a wave with a frequency of 20 Hz and a wavelength of 2.0 m?
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.
What is the frequency of a wave if 3 crests pass in 6 seconds?
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).
What is the frequency of a wave in 6 waves pass by in 2 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).
What is the frequency if five waves pass a certain point in 10 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.
How are frequency wave period related?
Period = 1 / frequency
What is the period of a wave if 20 crests pass an observer in 4 seconds?
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.
What is the frequency of the waves if 30 crests pass a dock in 5 seconds?
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).
What term is amount of time that it takes for one wave to pass by a given point?
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.
