Corrosion occurs at the anode, where the metal undergoes oxidation,

This process is the result of an electrochemical cell. 

In this fundamental mechanism, the anode facilitates the loss of electrons and the cathode facilitates the gain of electrons.

Allowing the overall chemical reaction of corrosion to proceed. 

Explanation

Because sound is just vibrating air, space has no air to vibrate and therefore no sound in a vacuum.

Sound waves below 20 Hz are known as infrasound.

Sound waves above 20 kHz are known as ultrasound

Sound waves transmit a medium such as a gas, liquid, or solid.

• The speed of sound in air is about 343 meters per second
• The sound travels at 1,481 m/s in water 
• The speed of sound in a vacuum is zero meters per second.
