Simply using the relation wavelength = velocity / frequency
So required wavelength = 25/5 = 5 m
Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz
It's 2, with same length-unit as the one in the speed
1/25 Hz
frequecy and period have an indirect relationship F=1/4s =.25 Hertz
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

1). Frequency = (speed) / (wavelength)2). Wavelength = (speed) / (frequency)3). Speed = (frequency) x (wavelength)Use #3:Wavelength = (35 cm/s) / (25 Hz) = 1.4 cm
Freq = Speed/Wavelength = 37.5/25 Hz = 1.5 Hz
The speed (v) of a wave = frequency (f) x wavelength (λ); v = ƒ• λ.To solve for wavelength when you have speed and frequency, divide speed by the frequency; λ = v/ƒ .λ = v/ƒ = 25m/s x 10Hz = 250m
The wavelength is 1.4cm. It's very simple. In order to find the answer is to know the formula. Wavelength=speed divided by frequency.
Note: The speed should be in units of cm/s rather than cm. The relation between the speed (v), frequency (f) and wavelength (λ) is: v = fλ. Therefore, f = v/λ = (500 cm/s) / (20 cm) = 25 Hz.
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".

You can use Plank's relation to calculate the energy of the absorbed photon.E = h.f = h.c/LgivenE = Energy of a photon in Joulesf = frequency of the photon in s-1c = speed of light in m/sL = wavelength of the photon in metreh = Planck constant = 6.62606957×10−34 J.s
It means the the wave has a speed of 25 vibrations per second
c is the speed of sound or the speed of light. You must know what you need. There is a relationship between the wavelength lambda and the frequency f. But forget the energy! c= lambda times f f is proportional to 1 / lambda. f = c / lambda lambda = c / f

1/4 or .25 F hope this helps
