Visible light, like other forms of electromagnetic radiation, travels through space at a constant speed known as the speed of light. In a vacuum (such as empty space), the speed of light is approximately 299,792,458 meters per second, often approximated as 3 x 10^8 meters per second.
This speed is an important fundamental constant in physics and is denoted by the symbol "c." It is worth noting that the speed of light can vary when passing through different mediums such as air, water, or glass, as it can be affected by the properties of those materials. However, in a vacuum, which is close to the conditions of space, visible light travels at the maximum speed possible.
