Answer:
Zero
Explanation:
There is no acceleration in light. Light cant be accelerated. Its speed is 299792458 m/s which is a universal constant. But approximately its 3×10^8 m/s .
We know that if direction of light changes then there will be change in direction of speed and thus it means its no longer speed* but now a velocity. And therefore, there will be acceleration.
But in which case direction of light changes. Answer is at event horizon. Event horizon is the place near black hole* where nothing can go out even light gets attracted. It means direction of light changes implies acceleration in light.
But, its still a matter of debate. Beacuse according to theory of relativity speed of light is constant.
