Wavelength times frequency is the speed.
To know the wavelength, you have to divide the speed by the frequency of the light.
wavelength = speed of light/frequency so we rearrange frequency = speed of light/wavelength Hopefully you can figure it out from here...
To find (wavelength): Divide (speed) by (frequency). To find (frequency): Divide (speed) by (wavelength).
Frequency = speed of light / wavelength
(Wavelength) x (frequency) = (wave speed) Wavelength = (speed) / (frequency) Frequency = (speed) / (wavelength) Note: This is true for any traveling wave, not only electromagnetic ones.
wavelength I will call lambda, frequency I will call f If f and lambda are the same then the velocities of the waves would be the same becuase v= lambda*f You know nothing about their phase angles or the amplitude of the waves though.
Wavelength times frequency is the speed. To know the wavelength, you have to divide the speed by the frequency of the 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.
the speed of light equals the frequency multiplied by the wavelength.
wavelength = speed of light/frequency so we rearrange frequency = speed of light/wavelength Hopefully you can figure it out from here...
To find (wavelength): Divide (speed) by (frequency). To find (frequency): Divide (speed) by (wavelength).
wavelength = c/frequency of light where c is the speed of light.
Inversely frequency = speed of light / wavelength
Frequency = speed of light / wavelength
Wavelength and frequency are inversely proportional.
(Wavelength) x (frequency) = (wave speed) Wavelength = (speed) / (frequency) Frequency = (speed) / (wavelength) Note: This is true for any traveling wave, not only electromagnetic ones.
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.
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.
