# Does light accelerate as it nears a black hole? [duplicate]

As light is affected by gravity ( gravitational lending and black holes), it would seem that gravity causes acceleration.

Acceleration has two parts: direction and magnitude. It is clearly evident that gravity affects the former of the two. It would seem that it does not affect the later component because light is currently at the universal 'speed limit' (not counting taychons).

What is going on here? Is the magnitude component affected by gravity?
