The frequency is 6 per 2 seconds = 3 Hz. The period is the reciprocal of the frequency = 1/3 second.
Frequency = 1 / (period) = 1/6th Hz

Speed = (wavelength) times (frequency) = (wavelength) divided by (period) = 30/5 = 6 meters per second
Period = 1 / (frequency) = 1 / 6th of a second = [166 and 2/3] millisecondsSpeed = (wavelength) x (frequency) = 6 x 3 = [18] meters per second
Frequency = reciprocal of (' 1 ' divided by) the period = 1 / (27 x 10-6) = 37,037.037 Hz (rounded)
The definiton of period (T) Is T = 1/f ; Therefore if you know that the period is 2.5 microseconds (=2.5 x 10-6) then the frequency is f=1/(2.5x10-6)= 4 x 105 Hz
Frequency and period are just reciprocals of each other, independent of wavelength, speed, and things like that. Period = 1 / (frequency) = 1 / (2 x 106) = 0.5 x 10-6 = 1/2 microsecond
The speed of a wave is the product of its frequency and its wavelength - so you simply need to divide the speed by the frequency.
6/30 seconds = 1/5 seconds = 0.2 Hz.
Wavelength = (wave speed) / (frequency) = (299,792,458)/(6,000) = 49.965 kilometers(in vacuum, rounded)
Speed of propagation v= (wavelength) x (frequency) = 2 x 6 = 12 m/sec
