The period is 4 [insert units here]. To get to this answer you use the equation v= λ*ƒ which basically means velocity is equal to lambda (wavelength) times frequency. Next you insert the speed where velocity is then you insert the wavelength and try to find the frequency. Once you get the frequency which should be 1/4 Hz then you use the proportion: period ~ 1/frequency and then you know that the period is 4.

What is the frequency of a wave if it has a wavelength of 2 m and a wave speed of 20 meters per second?
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
If a wave has amplitude of 2 meters a wavelength of 2 meters and a frequency of 10 Hz and a period of 1 second then at what speed is the wave moving?
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
What is the period of a wave traveling 5 ms if its wavelength is 20 m?
20/5 = 4 seconds
A wave has frequency of 50 Hz what is the period of the wave?
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds
What is the wavelength of 20 Hz?
need to know the speed of the wave at the speed of light 300,000,000 m/s 300,000,000 / 20 = 15,000,000 metres at the speed of sound 333 m/s 333 / 20 = 16.67 metres
What is the speed of a wave that has a wavelength 20 cm and a period of 0.5 s?
40 Hz
An ocean wave has a wavelength of 10 meters these waves pass by a stationary boat every 2o seconds what is the speed of the waves?
The speed of the wave can be calculated using the formula: speed = wavelength / period. In this case, the speed of the wave is 10 meters / 20 seconds = 0.5 meters per second.
What is the speed of a wave that has a wavelength of 20 cm and a period of 0.5 s?
The speed of a wave is equal to the product of wavelength x frequency. Just convert everything to standard units (wavelength to meters, frequency to hertz), multiply both, and you'll get the result, also in standard units (meters / second).
If a wave has frequency of 20 Hz what is the period of the wave?
.05 seconds
What is the frequency of a wave if it has a wavelength of 2 m and a wave speed of 20 meters per second?
Frequency = (speed)/(wavelength) = 20/2 = 10 Hz
A wavelength of 0.1 m and a frequency of 20 hz what would the wave speed be?
The wave speed can be calculated using the formula: wave speed = frequency x wavelength. In this case, the wave speed would be 2 m/s (20 Hz x 0.1 m).
What is the frequencey of a wave with the speed of 10 and wavelength 20?
Frequency = (speed)/(wavelength) = 10/20 = 1/2
If a wave has a frequency of 20hz and a wavelength of 2.5m what is the wave speed?
The wave speed can be calculated using the formula: wave speed = frequency x wavelength. Plugging in the values given, the wave speed would be 20 Hz x 2.5 m = 50 m/s.
If a wave has amplitude of 2 meters a wavelength of 2 meters and a frequency of 10 Hz and a period of 1 second then at what speed is the wave moving?
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
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 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 period of a wave traveling 5 ms if its wavelength is 20 m?
20/5 = 4 seconds
