### Inverse Relationships?

Can someone explain why the relationship of frequency and wavelength is inversely related? Also what are the units of frequency and wavelength?

if you refer back to the equation: speed of light(c)=wavelength(lambda) x frequency(v) you'll see that the product of wavelength times frequency must equal the speed of light which is a set value. Therefore when the wavelength decreases the frequency must increase and vice versa. The units for wavelength are usually nanometers (nm) or sometimes in meters (m) and the units of frequency are Hz or s^-1.

Also if you rearrange the equation to Wavelength = c/v if frequency (v) is larger than we know that wavelength is smaller and if its the opposite where frequency (v) is smaller the wavelength will be bigger. This also woks when Frequency (v) = c/wavelength. Also the units for wavelength are typically given in nanometers (nm) but in calculations we use meters (m) I believe so we would multiply the nanometers x 10^-9 to convert to meters. Frequency is Hz or s^-1 when doing calculations.

In the equation (c)=wavelength(lambda) x frequency(v), the speed (c) is a constant. Therefore if wavelength increases, frequency must decrease and vice versa because c must remain the same.

when there are an increased number of oscillations in a certain amount of time (frequency), the distance between the peaks (wavelength) decrease, and vise versa
