Wavelength and Frequency

Postby VahagnAldzhyan » Wed Oct 18, 2017 11:15 pm

Why is it that wavelength and frequency are inversely related?

We know that c = wavelength * frequency. Given that c is a constant, that tells us that if wavelength increases, then to compensate, frequency must decrease. Hope that helps!

we know that c= frequency x wavelength. c is a constant (speed of light), so from the first formula we can get that frequency=c/wavelength, from this you can see that frequency and wavelength are inversely proportional. In fact as the value of the wavelenght increases the value of the frequency decreases and vice versa

Yes exactly what the two above said, and it's easier to remember since c=2.99*10^8, so the the product of the frequency and wavelength of a beam will always be c or close to c, with the appropriate sig figs.
