No, sound would not travel faster than light even if there was no air. In fact, in a vacuum where there is no air or any other medium, sound cannot propagate at all.
Sound is a mechanical wave that requires a medium to travel through, such as air, water, or solids. It propagates by creating a series of compressions and rarefactions in the medium, which our ears perceive as sound. The speed at which sound travels depends on the properties of the medium, such as its density and elasticity.
In a typical scenario, sound travels through air at approximately 343 meters per second (about 1,235 kilometers per hour) at room temperature. However, in a vacuum, where there are no particles to transmit the wave, there would be no medium for sound to travel through. Therefore, sound cannot propagate in the absence of a medium like air or any other material.
On the other hand, light, which is an electromagnetic wave, does not require a medium to travel through. Light can travel through a vacuum at its maximum speed of approximately 299,792,458 meters per second (often rounded to 3.0 x 10^8 m/s), as determined by the fundamental constant of nature known as the speed of light (c). This is why light can propagate in outer space, which is mostly a vacuum.
In summary, sound requires a medium to travel through and cannot propagate in a vacuum. Light, being an electromagnetic wave, can travel through a vacuum at its maximum speed. Therefore, even in the absence of air, light would still travel faster than sound.
