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.
Frequency (1/seconds) x Wave Length (meters) = Speed (meters/sec. or m/s)
It is a constant which is equal to the speed.
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.
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.
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
Frequency (1/seconds) x Wave Length (meters) = Speed (meters/sec. or m/s)
The wavelength is equal to the speed divided by the frequency.
The length of each wave is 299,792,458 meters/the frequency of the wave .
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.)
The wavelength is calculated using the formula: Wavelength = Velocity / Frequency. Substituting the values given, we get Wavelength = 15 / 5.4 = 2.78 meters. Hence, the length of the wave is 2.78 meters.
Frequency and wavelength of a wave are inversely related: as frequency increases, wavelength decreases, and vice versa. This relationship is described by the wave equation: speed = frequency x wavelength. In other words, for a given wave speed, if frequency increases, wavelength must decrease to maintain the same speed.
velocity of a wave equals wave frequency times wave length.
It is a constant which is equal to the speed.
The length of the rope would be half the wavelength of the standing wave, so in this case, the rope would be 5 meters long. This is because the fundamental frequency of the standing wave has one full wavelength, which corresponds to half the length of the rope.
Frequency is inversely proportional to the wave length, thus saying the shorter the wave length the higher the frequency and vice versa.The frequency is the number of waves within a time period. As the frequency within that time period increases, the number of waves increases, therefore the width of each wave (wavelength) within that time period has to decrease. Therefore:As the wave length increases, the frequency decreasesAs the wave length decreases, the frequency increases
