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

How are wavelength frequency and energy are related?

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


What happens to the wavelength of a wave that slows down while retaining its original frequency?

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.
