For electromagnetic radiation, frequency x wavelength equals the speed of liqht, c, in a vacuum, which is 3.0 x 108 cm/s.
Formula: c = frequency x wavelength
Your given information is the frequency of 2.5 x 108/s.
Your known information is c, which is 3.0 x 108 m/s.
To solve for wavelength, do the following:
wavelength = c/frequency = (3.0 x 108 m/s)/(2.5 x 108/s) = 12 m
Cumilative Frequency is the running total of how many times something happened
Frequency is the amount of times a variable appears in a set. For example, if the number three appears 5 times it's frequency is five.
It is its frequency.
The meter was defined in 1790 as one ten-millionth (10 to the -7th power) of the Earth's quadrant passing through Paris. It was redifined - because the earth is not a sphere, after all, but an oblate spheroid - in 1960, as equal to 1,650,763.73 times the wavelength in a vacuum of the orange-red radiation of krypton 86. In other words, the meter is a length totally unrelated to anything in human experience, which supports the assertion that only a machine could love the Metric System.

For any wave, (wavelength) times (frequency) = (speed of propagation).For electromagnetic waves, (wavelength) times (frequency) = (speed of 'light')
Wavelength = (speed) divided by (frequency) Frequency = (speed) divided by (wavelength) Speed = (frequency) times (wavelength)
Wavelength times frequency gives the speed of the wave.
Wave speed = (Wavelength) times (frequency).
The product of (wavelength) times (frequency) is the speed.
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.
Speed = (frequency) times (wavelength) Frequency = (speed) divided by (wavelength) Wavelength = (speed) divided by (frequency)
Electromagnetic radiation can travel through "empty" space. Depending on the wavelength of the electromagnetic radiation, we call it "radio" or "microwaves" or "heat" or "light" or "UV" or "X-rays" or even "cosmic rays" - it's all different frequencies of EM radiation. The shorter the wavelength, the higher the frequency; in fact, the frequency times the wavelength is the constant "c", the speed of light.
The wavelength of waves travelling with the same speed would decrease if the frequency of the waves increases. This is because, speed of a wave is the product of the distance of the wavelength times the frequency of the wave. The velocity of a wave is usually constant in a given medium.
The speed is the product of wavelength and frequency.
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.
