That depends on what your light ray is traveling through. If through vacuum,
then its speed is 299,792,458 meters per second. If through anything else but
vacuum, then (299,792,458 meters per second) divided by (the index of refraction
of that material.
The speed of light is constant at about 300,000 km/s in a vacuum, so light does not experience acceleration.
A simple example of acceleration is a car speeding up from a stationary position at a traffic light. As the driver presses the gas pedal, the car's speed increases, showing acceleration.
As the car moves down the street, the velocity is positive. As it comes to a red light and stops, the velocity decreases to zero. Waiting at the red light, the acceleration is zero. When the light turns green and the car accelerates, the velocity increases from zero to a positive value, and the acceleration is positive.
Light does not have weight, acceleration, or mass. It does have direction and can exert force, as seen in phenomena such as radiation pressure.
Light does not accelerate as it always travels at a constant speed of 300,000 kilometers per second in a straight line, as per the laws of physics. This is because light does not have mass and therefore does not experience acceleration in the same way that objects with mass do.
When you are stopped at a light, and it turns green, you start to drive forward. That is acceleration.
The speed of light is constant in a vacuum and is approximately 299,792 kilometers per second. Light from a star travels at this speed from the star to Earth without acceleration.
The speed of light is constant at about 300,000 km/s in a vacuum, so light does not experience acceleration.
acceleration, I think
instantaneous acceleration is the acceleration at one point. yeah, it's true
Negative acceleration
speed of light is constant velocity and does not accelerate so there is no g force

It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
