Does light have a sound or an audio frequency?

Answer 1

No. The feequency range of visible light is far higher than that of audible sound.

Think of "middle C" in music. Its frequency is #440# cycles per second. Visible light is on the order of #10^{14}# cycles per second.

No, light is not an audio frequency or sound; light is an electromagnetic wave that can travel through a vacuum, whereas sound is a mechanical wave that needs a medium (such as air, water, or solids) to travel through.
