I don't remember the question exactly because I saw it in my final exam and I'm confused and don't know how to solve it exactly, so here's the question: 99 MHZ (99000000 HZ) frequency is produced to a 60 m base, find the wavelength. They didn't mention neither the velocity nor the time, and I know to find the time is to put 1/frequency. And does the velocity has the speed of light which is 3 x 10^8. Formula: V=wavelength x frequency As I told you I don't remember the question exactly but it looks like what I wrote above. I'm waiting for an answer as soon as possible. Thanks!
