frequecy and period have an indirect relationship F=1/4s =.25 Hertz

1/4 or .25 F hope this helps

Period = 1 / (frequency) = 0.04 second

It means the the wave has a speed of 25 vibrations per second

Definitely ultrasonic wave is longitudinal in nature. But the frequency is beyond human's hearing range. The frequency is higher than 25 kHz

25 waves are produced in 20 seconds , so 25 ÷ 20 = 1.25 waves in 1 second ... so the Frequency is 1.25 Hz

Simply using the relation wavelength = velocity / frequency So required wavelength = 25/5 = 5 m

It means that the wave makes 25 complete cycles per second. Each up and down pass together is a cycle, so there are 25 sets of them in a second.

The speed of the wave c = frequency f times wavelength lambda. c = 25 times 5 = 125 m/s, whatever that medium on what planet may be. Some formulas: Scroll down to related links and look at "Wavelength".

5 metres per second. V (velocity) = Distance/Time = 25/5 = 5
