What is the frequency of the wave moving at the rate of 40 cms. Its wavelength is 8 cm.?

Divide the speed by the wavelength.


If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?

IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).


Examples of the equation velocity equals frequency wavelength?

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.


How is wave length related to frequency fro waves moving at a constant speed?

Wavelength x frequency = speed of the wave.


How fast is a wave moving if its wavelength is 10meters and its frequency is 110Hz?

The speed of a wave is equal to its wavelength times its frequency. Since you are using SI units, the answer will be in meters/second.


What is the correlation between wavelengths and frequency?

Wavelength = wave speed/frequency Frequency = wave speed/wavelength (Wavelength) x (Frequency) = Wave speed


How does frequencey relate to wavelength?

Frequency = (wave speed) divided by (wavelength)Wavelength = (wave speed) divided by (frequency)Wave speed = (frequency) multiplied by (wavelength)


What is the frequency of a wave moving at 24 ms with a wavelength of 3 m?

8Hz


What is A change in the observed wavelength or frequency of a wave that occurs when the source of the wave or the observer is moving?

Doppler Effect :)


2 wave have the same frequency the faster of the two waves will have what?

Wavelength x frequency = velocity, so if the frequency is the same for two waves moving at different velocities, the faster wave must have a longer wavelength.


What is the quantitative relationship between frequency and wavelength?

speed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelengthspeed (of the wave) = frequency x wavelength


What is the frequency of a wave moving at 24 ms with wavelength of 3 m?

8 Hz
