Finding wavelength from frequency?
Do I need to convert the frequency to Hz (the questions are all in MHz or kHz) before using the formula? i need to have my answer in meters.

The formula you need is c = (lambda)(nu), where c is the speed of light (in m/s), lambda is the wavelength (in m), and nu is the frequency (in 1/s).
You can rearrange this equation to find that (lambda) = c/(nu). The speed of light is generally expressed in m/s, so yes, you should convert all frequency measurements to Hz (1/s). As long as c is in m/s and nu is in Hz, your wavelengths will be in meters.
