The speed of light is fixed and so the wavelength and the frequency of light are related like this:
wavelength * frequency = speed of light
You just have to be careful your units match up. Often wavelengths of light are listed in nanometers, or nm, while the speed of light is often given in meters per second, or m/s. Make sure everything is in terms of meters or your answer will be way off. Frequency is almost always given in terms of 1/seconds, which is also called a Hertz. See the Web Links for more information about the electromagnetic spectrum.
The equations for wavelength and frequency of light are:
- Wavelength (λ) = c / f, where c is the speed of light (3.00 × 10^8 m/s) and f is the frequency of the light wave.
- Frequency (f) = c / λ, where c is the speed of light and λ is the wavelength of the light wave.
E=hv
E, is the energy, in joules, H, is a fundamental physical
of a quantom of radiation. constant now known as Plank's
constant; h=6.626x10(to the power of -34)
V, is the frequency, in s-1, of the
radiation emitted.
Wavelength lambda and frequency f are connected by the wave speed c of the medium. c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s. c can be light waves or electromagnetic waves = 299 792 458 m/s. The formulas are: c = lambda x f f = c / lambda lambda = c / f
The equation is c=wf where c is the speed and w is the wavelength and f is the frequency.
The speed of electromagnetic radiation is c= 3E8 meters/second in space.
(Frequency) x (Wavelength) = Speed of light.
Note carefully that the "speed of light" in the equation above is the speed of light in the medium that the wavelength is measured in. In vacuum it will be the famous constant "c", but when light travels through any sort of material it's speed is slowed and its wavelength shortened by a factor called the refractive index of the medium. Because wavelength and speed are reduced by the same factor the equation still holds. Light's frequency is not affected by the medium.
Wavelength * Frequency = 3*108 m/s (speed of light)
All electromagnetic radiation (such as radio waves) travel at the speed of light.
A more general equation would be:
Wavelength * Frequency = Propagation speed
For electromagnetic radiation . . .
Speed in the present medium = (wavelength in the present medium) x (frequency)
Wavelength = (speed) / (frequency)
Frequency = (speed) / (wavelength)
c = ƒ• λ, where c is the speed of light in a vacuum, 3.0 x 108m/s, f is the frequency in Hz, and λ is the wavelength in meters.

What is the relationship between wavelength and frequencyand the speed of light?
Light with a lower frequency will have a longer wavelength. Frequency and wavelength are inversely proportional to each other (i.e. as one increases, the other decreases and vice-a-versa). The product of frequency and wavelength is the speed of light.
What is the formula relating speed of light frequency and wavelength?
The formula relating the speed of light (c), frequency (f), and wavelength (λ) is: c = fλ. This formula shows that the speed of light is equal to the frequency multiplied by the wavelength.
A helium neon laser emits light of wavelength 633 nm Light from an argon laser has a wavelength of 515 nm Which laser emits the higher frequency light?
according to the wave theory of light,we have the relation that wavelength is inversely proportional to the frequency,therefore the electromagnetic wave with the lower wavelength will have higher frequency..
Is frequency a characteristic of visible light that does not depend on the light's wavelength?
No, frequency and wavelength of visible light are directly related through the speed of light in a vacuum. The frequency of visible light waves is inversely proportional to their wavelength: shorter wavelengths have higher frequencies and vice versa. This relationship is described by the equation c = λν, where c is the speed of light, λ is wavelength, and ν is frequency.
What is the frequency of an electromagnetic wave that has a wavelength of 300000 kilometers?
The frequency of an electromagnetic wave is calculated using the equation: frequency = speed of light / wavelength. Given the speed of light is approximately 300,000 km/s, you can calculate the frequency by dividing the speed of light by the given wavelength of 300,000 kilometers. The resulting frequency will be in hertz (Hz).
What is the general equation for Wavelength?
The general equation for wavelength is: Wavelength = Speed of light / Frequency.
How does the wavelength of light compare to it's frequency?
The wavelength of light is inversely proportional to its frequency. This means that light with a shorter wavelength will have a higher frequency, and light with a longer wavelength will have a lower frequency. In other words, as the wavelength decreases, the frequency increases.
What happenes to the frequency of light when its wavelength increases or decreases?
When the wavelength of light increases, the frequency decreases. Conversely, when the wavelength decreases, the frequency increases. This relationship is described by the equation: frequency = speed of light / wavelength.
What equations tell us how fast a wave travels?
The speed of a wave can be determined by the equation: speed = frequency x wavelength. This equation relates the speed of a wave to its frequency and wavelength. Additionally, the wave equation, c = λf, where c is the speed of light, λ is the wavelength, and f is the frequency, can be used to determine the speed of electromagnetic waves in a vacuum.
How could you find the wavelength of light if you knew its speed and frequency?
You can use the equation: wavelength = speed of light / frequency. Given the speed of light (3.00 x 10^8 m/s) and the frequency of the light source, divide the speed of light by the frequency to determine the wavelength of the light.
What is the formula for converting frequency of light into wavelength?
wavelength = c/frequency of light where c is the speed of light.
What is the relationship between wavelength and frequencyand the speed of light?
Light with a lower frequency will have a longer wavelength. Frequency and wavelength are inversely proportional to each other (i.e. as one increases, the other decreases and vice-a-versa). The product of frequency and wavelength is the speed of light.
How do the wavelength and frequency of red light compare to the wavelength and frequency of blue light?
Red light has a longer wavelength and lower frequency compared to blue light. Blue light has a shorter wavelength and higher frequency, which is why it appears bluer in color to the human eye.
How do you calculate light wavelength to frequency?
You can calculate frequency from wavelength using the equation: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second. By dividing this speed by the wavelength of light in meters, you can determine the frequency in hertz.
Which light has the longest wavelength and the shortest frequency?
Red light has the longest wavelength and the shortest frequency among the visible light spectrum.
How could you find the wavelength of light if you knew it's speed and frequency?
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the light.
How are the frequency and wavelength of light related?
The frequency of light is inversely proportional to its wavelength. This means that as the frequency of light increases, its wavelength decreases, and vice versa. This relationship is described by the equation: speed of light = frequency x wavelength.
