This question is very hard to decipher. But I'm going to assume you are talking about the wavelength of signals with those frequencies. To determine the wavelength in meters, divide the speed of light (in meters per second) by the frequency. The speed of light, c, is 3E8 m/s. (299,792,458) Let's try a few. a)3 GHz = 3E9 Hz. So, 3E8/3E9 = 1E-1 = 0.1 m (which equals 10 cm or 100 mm). b) 3 MHz = 3E6 Hz. So, 3E8/3E6 = 1E2 = 100 m. c) 3 KHz = 3E3 Hz. So, 3E8/3E3 = 1E5 = 100,000 m (which equals 100 km). For a) Where E = 10 X 3E8= 3 x 108 meaning 300,000,000(approximately) 3E9 = 3 GHz x 109, meaning 3,000,000,000
