Frequency = speed/wavelength
Period = 1/frequency = wavelength/speed = (3,000,000)/(300,000,000) = 0.01 second
Wavelength = speed/frequency = 3 x 108/100 x 106 = 3 meters (in vacuum)

If its wavelength is 50 meters with a period of 6.5 seconds it means it is traveling at 50 meters every 6.5 seconds or 50/6.5 = 7.7 meters/sec.
Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
The frequency is 1/5 = 0.2 Hertz. The wavelength is irrelevant in this question.
Period = Wavelength/Speed = 10mm/50,000 mm/s = 1/5000 s or 0.0002 seconds
Celerity speed of a deep water wave is 16.6 meters per sec. with a wavelength of 166 meters.
If a wave is traveling at 5 meters per second (assuming that is what the question meant) and its wavelength is 20 meters, consider standing beside the wave and watching it pass. As the wave is 20 meters long and it is moving at 5 meters per second, it will take 4 seconds for the full cycle of the wave to pass an observer. That means its frequency is one cycle per 4 seconds. And - surprise! - that's the period of the wave. The period of the wave is 4 seconds.
Wavelength is in meters, the frequency is in hertz. period is in seconds and the wave speed is in meters per second.
20/5 = 4 seconds
Frequency = (speed) / (wavelength) Period = 1 / (frequency) = (wavelength) / (speed) = (0.01 meter) / (50 mi/sec x 1609.344 meters/mi) = 0.1243 microsecond (rounded)
The speed of the wave is equal to wavelength x frequency. You can calculate the frequency, in this case, as 1 / period.
A pendulum with a period of five seconds has a length of 6.21 meters.
Wavelength = (speed)/(frequency)Frequency = 1/periodso wavelength = (speed) x (period)Speed = (20 meter/min) x (1 min/60 sec) = 1/3 meter/secWavelength = (speed) x (period) = (1/3 meter/sec) x (30 sec) = 10 metersThe correct choice is a .
