It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.

What is the product of the frequency and the wave length of a wave?
Frequency (1/seconds) x Wave Length (meters) = Speed (meters/sec. or m/s)
What can you observe with the values of the product of frequency and wave length in the spectra?
It is a constant which is equal to the speed.
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.
How fast is a wave moving if its wave length is 10 meters and its frequency is 110 Hz?
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.
What is the relation between speed frequency and wave length?
wave length and frequency are the product of the wave speed, so the wave speed is a constant variable and the other two are inversely proportional the wave length increases, as the frequency decreases
What is the product of the frequency and the wave length of a wave?
Frequency (1/seconds) x Wave Length (meters) = Speed (meters/sec. or m/s)
How is a waves frequency related to a waves length?
The product of the wave's frequency and the wave's wave length is equal to the speed of propagation of the wave.
Relationship between frequency wave length and wave speed?
The wavelength is equal to the speed divided by the frequency.
What are the differences between frequency and wave length?
The wavelength is the size of the wave in meters. The frequency is the number of waves that occur in a scond.
What is the speed of a wave if it has a frequency of 4hz and a wave length of 8 meters?
The speed of the wave will be 32 metres /sec .
What are the sizes of each waves in the electromagnetic spectrum?
The length of each wave is 299,792,458 meters/the frequency of the wave .
What is the velocity of a wave that has frequency of 22 hz and a wave length of 4m?
88 meters per second
What is the speed of a wave that has a frequency of 250 hertz and a length of 1.3 meters?
The equation to use in this case is:speed (of the wave) = wavelength x frequency If the frequency is in hertz, and the wavelength is in meters, the speed will be in meters/second.
What is the speed of a wave with a wavelength of MM and a frequency of Hz?
The speed of a wave is equal to the product of its wavelength and its frequency. (If you want to have the speed in meters/second, convert the wavelength to meters first.)
What is the velocity of a wave with a frequency of Hz and a wavelength of 2 m?
Just multiply the frequency by the wavelength. In this case, the product will be in meters per second.
If a wave has a wavelength of 9 meters and a period of 0.006 what is the velocity of the wave?
The speed of the wave is equal to wavelength x frequency. You can calculate the frequency, in this case, as 1 / period.
If a wave has a low frequency how do you describe the wave length?
The frequency of a wave is not directly related to the wave length. A low frequency wave or a high frequency wave may be either long-wave or short-wave.
