Diffraction affects radio and television signals. Long wave radio signals are much less affected by buildings, hills, tunnels etc. than those of short wave or VHF radio, or television.

suggesting it is the result of the interaction of radio waves with the plasma and the magnetic field of the pulsar. "A typical diffraction pattern would produce evenly spaced fringes if we just ...

It looks like there is only one piece of information in the question but it says that the wave is a radio wave and all radio waves (and EM waves) travel at the speed of light – \(3 \times 10^{8} ...
