    a) red light
    red lights are an example of an electromagnetic wave. visible lights are the only electromagnetic waves we can actually see on the spectrum. red, in particular has the biggest wavelength.

    b) ocean waves
    ocean waves are not an electromagnetic wave. in fact, it’s a mechanical wave. electromagnetic waves can travel through a vacuum, that is empty space, but mechanical waves cannot.

    c) sound waves
    sound waves are also not an electromagnetic wave. it’s a mechanical wave. you cannot hear electromagnetic waves.

    d) earthquakes
    an earthquake is also not an example of electromagnetic waves. it’s a mechanical wave.

    hope this helps!
