Its' reciprocal. 400 kilohertz.

electromagnetic wave is not a sound wave
Its' reciprocal. 400 kilohertz.
The reciprocal of the period of ANY wave is the wave's frequency.
The period of a 261 Hertz sound wave is 0.000383 Seconds
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.

The amplitude of a sound wave is what we perceive as volume. It is the amount of energy "carried" within each period of the wave.

No, a sound wave is a compressional wave.
In theory it can but requires infinite bandwidth. A square wave (or pulse) is a combination of the fundamental frequency and the odd harmonics. If you send a square wave of 1kHz, you need to also be able to send 3kHz, 5kHz, 7kHz, 11kHz ....... etc. Since the bandwidth allowed for most SSB transmissions only allow up to 3kHz bandwidth, all you get is the fundamental of a 1kHz sin wave. On the other hand, if you send a 200Hz tone you can send 200Hz, 600Hz, 1kHz, 1.4Hz, 1.8Hz, 2.2kHz 2.6kHz and this combination will look a lot more like the original 200Hz square wave tone.

No. A sound wave is a pressure wave.
