Is the speed of light directly proportional to the distance traveled?
No, the speed of light is not directly proportional to the distance traveled. The speed of light in a vacuum is constant, known as "c," and is approximately 299,792,458 meters per second. This means that light always travels at the same speed regardless of the distance it travels.
The relationship between speed, distance, and time is given by the equation:
Speed = Distance / Time
In this equation, speed is the rate of change of distance over time. If distance and time are directly proportional, then the speed will be constant. However, this is not the case with the speed of light, as it remains constant regardless of the distance traveled.
To calculate the time it takes for light to travel a certain distance, you can use the formula:
Time = Distance / Speed
For example, if you have a distance of 300,000 kilometers, you can divide it by the speed of light to find the time it takes for light to travel that distance.
