What is the difference between a sound wave and radio of same frequency 15kHz?

Sound waves and radio waves are both mechanical waves, but they have different properties. Sound waves travel through a medium, such as air or water, while radio waves can travel through a vacuum. Sound waves have a lower frequency than radio waves, typically between 20 Hz and 20 kHz, while radio waves have a higher frequency, typically between 3 kHz and 300 GHz.

The main difference between a sound wave and a radio wave of the same frequency is their wavelength. The wavelength of a wave is the distance between two consecutive peaks or troughs. The wavelength of a sound wave is much shorter than the wavelength of a radio wave of the same frequency. For example, a 15 kHz sound wave has a wavelength of about 2.3 cm, while a 15 kHz radio wave has a wavelength of about 20 km.

Another difference between sound waves and radio waves is their amplitude. The amplitude of a wave is the maximum displacement of the wave from its rest position. The amplitude of a sound wave is typically much smaller than the amplitude of a radio wave of the same frequency. This is because sound waves are more easily absorbed by objects than radio waves.

Finally, sound waves and radio waves have different speeds. The speed of sound in air is about 343 m/s, while the speed of radio waves is about 299,792,458 m/s. This means that radio waves travel much faster than sound waves.

In summary, sound waves and radio waves are both mechanical waves, but they have different properties. The main differences between sound waves and radio waves are their wavelength, amplitude, and speed.
