Frequency = (speed)/(wavelength) = 12/2 = 6 per second = 6 Hz.
Note:
The question doesn't give enough information to describe the velocity. "12" is not
a velocity, but it can be a speed, and we've assumed that it is. Fortunately, 'speed'
is all we need to answer the question.
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
velocity = frequency / wavelength, I believe.
Velocity = Frequency * Wavelength. If the wavelength increases and the frequency stays the same, then the speed of the wave will increase.
Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.
velocity = frequency multiply wavelength Rearrange the equation to find the frequency
The velocity=distance/time ,, Suppose that the distance covered is one complete vibration therefore the distance is called wavelength and the time is called periodic time then velocity=wavelength/periodic time also frequency= 1/periodic time therefore the velocity=wavelength*frequency
Wavelength*Frequency = Velocity of the wave. or Wavelength/Period = Velocity of the wave.
the velocity of a wave is given by frequency*its wavelength
velocity = frequency × wavelength frequency = velocity / wavelength f= 100 /20 f= 5 Hz
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.
