For an electromagnetic wave the velocity of the wave is 300Mm/s.
That would be a 'radio' wave with a wavelength about 71/2 times the Earth's circumference.
They could undergo constructive interference in which the amplitudes of the two waves combine. For example, a wave with an amplitude of 2 units overlaps with another wave with an amplitude of 2 units, the overlapping amplitude will be 4 units. They could also undergo destructive interference in which the amplitude of one wave is 2 units and the amplitude of the second wave is -2 units. At the point where they meet, the combined amplitude will be zero.
Period = (4 seconds) / (2 waves) = 2 seconds per wave Frequency = (2 waves) / (4 seconds) = 0.5 Hz.
