Why can radio waves travel through space but sound cant?

Sound waves require a medium, such as air or water, to travel. In the vacuum of space, there is no air or water to carry sound waves, so they cannot travel. Radio waves, on the other hand, are electromagnetic waves that do not require a medium to travel. They can travel through the vacuum of space at the speed of light.

Here are some additional details about the differences between sound and radio waves:

* Sound waves are mechanical waves, which means that they involve the physical vibration of particles. Radio waves, on the other hand, are electromagnetic waves, which means that they do not involve the physical vibration of particles.

* Sound waves have a much lower frequency than radio waves. The frequency of a wave is the number of times per second that the wave oscillates. Sound waves typically have frequencies between 20 and 20,000 hertz (Hz), while radio waves have frequencies between 300,000 Hz and 300 billion Hz.

* Sound waves travel at a much slower speed than radio waves. The speed of sound in air is about 340 meters per second, while the speed of light is about 300,000 kilometers per second.

These differences in frequency and speed mean that sound waves cannot travel through space but radio waves can.
