Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.
The speed c = 40 meters per second and the frequency f = 120 Hz. The wavelength lambda = c / f. Lambda = 40 / 120 = 0.3333333333 meters.
Since the wave speed equation tells us that the speed of a wave (meters per second)is equal to the wavelength (meters) multiplied by the wave frequency (Hertz), you should be able to calculate your answer by multiplying 12 and 100. Don't forget to include the units that your answer will be measured in!
Wave speed = (wavelength) x (frequency) = (20) x (50) = 1 kilometer per second.
That's the magnitude of the wave's velocity. We can't complete the description
of the velocity because we have no information concerning its direction.
velocity 100 meter per second
wavelength 20 m
so formula is V=f*wavelength (lambda)
So
frequency=100/20=5Hz
To find the frequency of wave, we have a formula
v = f(lambda)
Where,
Lambda = wavelength
f=v/lambda
f = 100 × 10^-3/20
f = 0.005Hz
velocity = frequency × wavelength
frequency = velocity / wavelength
f= 100 /20
f= 5 Hz
Please use the equation:
speed (of the wave) = frequency x wavelength
=====================
5Hz
Wavelength = (speed) / (frequency) = 20/4 = 5 meters.
Speed is not measured in milliseconds.
the velocity of a wave is given by frequency*its wavelength
The velocity of the wave
Velocity equals frequency times wavelength
v = frequency x wavelength v is the velocity of the wavelength
you find out a waves speed by taking the wavelength and divide it by it's wave period or how long it takes for the wave to complete a full wavelength. This is what my textbook said. Speed=Wavelength ×Frequency
velocity = frequency × wavelength frequency = velocity / wavelength f= 100 /20 f= 5 Hz
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
the velocity of a wave is given by frequency*its wavelength
The velocity of the wave
velocity = frequency x wavelength
Velocity equals frequency times wavelength
Wave velocity in general = frequency x wavelength As the velocity of the wave remains constant then frequency and wavelength are inversely related So as the wavelength becomes shorter then frequency becomes larger or higher
velocity = frequency x wavelength
velocity = frequency / wavelength, I believe.
v = frequency x wavelength v is the velocity of the wavelength
As the basic formula of all types of waves is (Velocity of a wave=the product of the wavelength of it and its frequency). In this case, frequency of a certain wave is constant and the velocity is decreasing. And as the velocity is directly proportional to the wavelength, the wavelength of the wave shortens as a result.
Energy of light photons is related to frequency as Energy = h(Planck's constant)* frequency Frequency = velocity of wave / wavelength So energy = h * velocity of the wave / wavelength
