Is wavelength of an electromagnetic wave directly or inversely related to frequency?

Expert Answers

We can look at the formula that relates wavelength to frequency to determine the answer.  The formula is

lambda = c / nu

where lambda is the wavelength, c is the speed of light (3.00 x 10^8 m/s) and nu is the frequency of the electromagnetic radiation.  By looking at the equation,...

We can look at the formula that relates wavelength to frequency to determine the answer.  The formula is

lambda = c / nu

where lambda is the wavelength, c is the speed of light (3.00 x 10^8 m/s) and nu is the frequency of the electromagnetic radiation.  By looking at the equation, we see that lambda is in the numerator on one side of the equation and nu is in the denominator on the other side.  When this happens, this indicates that the wavelength is inversely proportional to the frequency.  You can test this idea by plugging in values for the freqency to see that as the frequency increases, the wavelength decreases.
