Do sound waves travel in a vacuum? Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Radio is a form of electromagnetic radiation just like light and can therefore travel through […]

Does coiling a wire increase resistance? If you coil a wire its resistance does not change. As that is purely down to the material that the wire is made out of and the diameter, temperature coefficient and the length of the wire. Coiling the wire will however will change the inductance of the wire. Is […]
