Explanation:
Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.Light from distant galaxies and even the microwave cosmic background radiation are examples of EM energy having travelled to us from across the universe. Yes, waves can travel much further than their wavelengths.the distance a radio wave travels in a vacuum, in one second, is 299,792,458 meters (983,571,056 ft), which is the wavelength of a 1 hertz radio signal. A 1 megahertz radio wave (mid-AM band) has a wavelength of 299.79 meters (983.6 ft).
