Okay, so since we have to do it, let's do it. So it says what is the wavelength in meter per snap of an fm radial wave with frequency nu equals 102.5 megahertz. And we're looking for the wavelength. So we know what is the equation? C, nu, that's wavelength. And we also know what C is. What is that? Like that. 3.0 times 10 to the 8 meters per second, the speed of light in the vacuum. And we're looking for wavelength. So we're going to have to isolate the wavelength variable. Like that. So that is this, well, this says meters per second. And we're looking for meters. And this is in megahertz. What is that? This doesn't compute, right? So remember, per once is another way of saying per second. So of course, mega is a prefix that we're going to have to convert to averse. So let's go ahead and do that first. Okay, so you guys remember what the mega is? 1 times 10 to the 6 hertz is 1. 1 times 10 to the 6 hertz is 1. So when you calculate that out, should be 1.205. 1 times 10 to the 8 hertz. What would you guys got? So now we're just going to plug in Chut because we've got that. But we've got to remember that hertz is per second. So if you want to, you can go ahead and do that already. So let's see what we can do. 3.0 times 10 to the 8 meters per once that amp. And remember, we want to cancel out our seconds. So what are we going to have to do with this thing of, okay, because this is just a conversion factor saying this many cycles per second. Okay, everybody's okay with that. So for me when I was in your spot, these were kind of difficult for me because nobody really ever showed me to do it this way. But I think this is what we're doing. What'd you guys do? 2.9, 2.9, 2.7, right? Why is that? Because we started out with forces. Okay, so the 102.5, it's got a wavelength of about 30 meters. Any time you listen to 102.5 or whatever, remember that. Any questions on this one? I don't even know, it's 1.0.2.5 even a station. I don't think so. Probably somewhere.
