Why is the wavelength of light multiplied by the frequency of light is equal to the speed of light?

v=fλ (velocity (m/s)=frequency (s^-1) * wavelength (m)
When dealing with light v=hf is also useful (same derivation as for above), where h is the Planck constant.

∙ 9y agoFor any wave form, the wavelength multiplied by the frequency is the speed of the wave.

Because that statement is true for ANY wave phenomenon, not only light.

What is the formula relating speed of light frequency and wavelength?
the speed of light equals the frequency multiplied by the wavelength.
How do wavelength and frequency relate to the speed of light?
c=lamda*f c is a constant, which is the speed of light, lamda is the wavelength which the light is traveling at, and f is the frequency of the light. All light travels at the speed of light no matter what colour, however ever colour tavels at different wavelengths and frequencies.
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 wavelength of an electromagnetic wave that has a frequency of 2.45 109 Hz in a vacuum (The speed of light in a vacuum is 3.00 108 ms.)?
You need to divide the speed of light (in m/s) by the frequency (in Hz, which is equal to 1/s) to get the wavelength (in meters).
Which type of visible light has the longest wavelength?
The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.
What is the formula relating speed of light frequency and wavelength?
the speed of light equals the frequency multiplied by the wavelength.
How do you convert heartz to meter?
The frequency of a radio wave in Hertz (cycles per second) multiplied by the wavelength of the radio signal (in meters) is always equal to the speed of light, which is equal to The speed of light has the symbol "c". So Frequency/c = wavelength, and wavelength/c = frequency. == ==
What is the wavelength of a light-wave that has a frequency of 1500000 Hz?
Use the fact that the frequency, multiplied by the wavelength, is equal to the speed of a wave. In a vacuum, light will move at 300 million meters/second; just divide this speed by the frequency.
What is the principle difference between radio waves and visible light?
Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )
The speed of a wave is its wavelength multiplied by its what?
The speed of light is fairly constant. 3.0X10^8 meters per second. Sounds' speed varies with conditions , but like light it is not changed by wavelength/frequency or amplitude.
How are they frequency and wavelength of light related?
Both have something to do with lightThanks for that, and go to your room now.When the frequency is multiplied by the wavelength, the product isalways the same number ... 299,792,458 meters per second ... thespeed of light.
What determine the color of a light wave?
Its wavelength (or frequency).
What is the relationship between energy of electromagnetic radiation and its wavelength?
For a single photon, the energy is equal to the frequency, multiplied by the reduced Plank constant. Since the frequency is equal to the speed of the wave divided by the wavelength, for the wavelength this becomes: energy = (reduced Planck constant) x (speed of light) / wavelength. Note that this is for a single photon only; it says nothing about the light from a flashlight, some other lamp, the Sun, etc., which consists of lots of photons.
What happens to the wavelength of lights as the frequency increases?
For any wave (not just light), the product of the wavelength and the frequency is equal to the speed of the wave. For light in a vaccum, the speed is constant (ca. 300 million m/s). - thus, as the frequency increases, the wavelength gets shorter.
What is the formula for converting frequency of light into wavelength?
wavelength = c/frequency of light where c is the speed of light.
What happenes to the frequency of light when its wavelength increases or decreases?
wavelength = speed of light/frequency so we rearrange frequency = speed of light/wavelength Hopefully you can figure it out from here...
What is the speed of the solar signal in water with a frequency of1000 hertz and wavelength of 1.5?
I assume that a "solar signal" means light. Light moves at approximately 262 million meters per second in water, regardless of the frequency or wavelength of the light. Also, if light has a frequency of 1000 Hz, then it has a wavelength of 300 kilometers. The speed of light, c, is equal to the product of the frequency and the wavelength. In other words, c=f*w
