Noticing the delay of light in everyday situations is not a common experience because the speed of light is incredibly fast. In a vacuum, light travels at approximately 299,792,458 meters per second (or about 300,000 kilometers per second), which means it covers vast distances in a fraction of a second.

While there are instances where one might perceive a noticeable delay in the propagation of light, they usually occur in specific circumstances, such as over long distances or in situations involving significant time intervals. For example, if you observe a distant lightning strike and notice a delay between seeing the flash and hearing the thunder, you are perceiving the difference in the speeds of light and sound. Sound travels much slower than light, which creates the noticeable delay.

In everyday scenarios, however, the speed of light is typically so fast that any delays are not perceivable to human senses. Our visual perception is adapted to process light and its interactions with objects in real-time, without noticeable delays.
