I am having some trouble with inverse variations, I would appreciate any sort of help.
The frequency of a radio wave varies inversely as its wavelength. If a 200 meter wave has a frequency of 3000 kilocycles, what is the wavelength of a wave that has a frequency of 2000 kilocycles?
y=k/x
200 = 3000/x
Then cross multiply to get 200x = 3000 and x = 15
Then take 2000/15 = 133.33
I'm not sure that I am getting the numbers in the right locations.
Thanks.
