The speed of electricity, light, and sound all travel at different rates through various mediums:
Speed of Electricity: Electricity is the flow of electric charge through a conductor, such as a wire. The speed of electricity varies depending on the material of the conductor and the conditions. In general, electricity moves at a significant fraction of the speed of light but is slower than the speed of light in a vacuum. In most practical situations, the speed of electricity in a conductor is much slower than the speed of light. It typically ranges from about 50% to 99% of the speed of light in a vacuum.
Speed of Light: The speed of light in a vacuum is approximately 299,792 kilometers per second (about 186,282 miles per second). In scientific notation, it is represented as approximately 3.00 x 10^8 meters per second. Light travels at this constant speed in a vacuum, and nothing with mass can travel faster than this speed according to our current understanding of physics.
Speed of Sound: The speed of sound depends on the medium through which it travels. In air, at room temperature and standard atmospheric pressure, the speed of sound is approximately 343 meters per second (about 767 miles per hour). However, the speed of sound can vary significantly in different substances. For example, sound travels faster in water and even faster in solids like steel.
In summary, the speed of electricity is generally slower than the speed of light but faster than the speed of sound in air. The specific speeds for each can vary depending on the medium through which they propagate.
