∙ 15y agoThe speed c = 40 meters per second and the frequency f = 120 Hz. The wavelength lambda = c / f. Lambda = 40 / 120 = 0.3333333333 meters.

∙ 14y agoSince 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!

∙ 11y agoWave 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

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
Wavelength multiplied by the Frequency of the wave .
the velocity of the wave -apex
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 = frequency x wavelength
velocity = frequency / wavelength, I believe.
Velocity equals frequency times wavelength
Wavelength multiplied by the Frequency of the wave .
the velocity of the wave -apex
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
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
