Best Answer

For any wave:speed = wavelength x frequency

So, you must simply calculate the frequency first (it is 1/period), then multiply that by the wavelength.

What is the speed of the waves if the wave period is 4 seconds?

you have to know the wave length.


How do the properties of waves affect the speed frequency and period of waves?

Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)


A water wave rises and falls twice every four seconds What is the period of the wave What is its frequency?

Period = (4 seconds) / (2 waves) = 2 seconds per wave Frequency = (2 waves) / (4 seconds) = 0.5 Hz.


In describing waves is the mathematical symbol used the waves period this quantity has units of?

T, seconds


How is a waves frequency related to a waves length?

The product of the wave's frequency and the wave's wave length is equal to the speed of propagation of the wave.


What is the formila for frequency in waves?

Frequency = Speed/Wave length.


How t find a waves frequency?

1/T, where T=period in seconds.


What is the frequency and time period and wave length of waves if 10 waves pass every 20 seconds?

To get the frequency, divide the number of waves (10) by the time it takes for those waves to pass (20). The answer is in hertz.The period is the reciprocal of the frequency. There is not enough information to determine the wavelength.


What is the period of the waves that take 2 seconds to make a complete cycle?

depends on what type of vibration the vibrations that are counted in atomic closcks are multiple billions of times a second and the vibration of the earth or RESONATION is 6hertz im pretty shure and the vibration of the movement of the earth is one pulse every year a rediculusly long wavelength be more spesific


If a radio wave has a period of 1 us what is the waves period in seconds?

If a radio wave has a period of one then the period wave or two would be 2. This is math.


An ocean wave has a wavelength of 10 meters these waves pass by a stationary boat every 2.0 seconds the speed of the waves is?

5m/s...


What are the things that can be measured about waves?

Speed, wavelength, frequency, period, amplitude, intensity.
