1. The problem statement, all variables and given/known data
A radar receiver can be tuned to detect signals are different wavelengths. If the frequency difference between the minimum and maximum wavelength is 10 GHz and the minimum detected wavelength is 4910µm. What would be the maximum wavelength?

2. Relevant equations
λƒ=c

3. The attempt at a solution
I attempted to use the above equation to convert 10GHz to wavelength and then add to the minimum wavelength but this appears to be incorrect and I'm struggling to figure out the proper way to go about this. I know I must be missing something very basic

Does the minimum wavelength correspond to the minimum or to the maximum frequency ?

Ah! minimum wavelength corresponds to maximum frequency! Thank you! That little error was throwing quite the wrench into the problem
