Explanation In the resulting waveform, the areas where the amplitude is zero they are known as nodes and the points where waveform varies from twice the amplitude of its constituent waveforms in both directions they are knows as antinodes. There is one antinode between the two respective nodes. The number of antinodes is equal to the number of harmonics. The strings is fixed at the both ends and the standing wave has three nodes means there is node on each ends and one node is at the middle of the string, so there is only one antinode between each pair of nodes. As the number of harmonics is equal to the number of antinodes, so when the number of harmonics is doubled the number of antidotes is also doubled. Now the number of antinodes is 4 as the harmonic are doubled

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.
