Morphology
The meaning 'the maximum speed at which light travels' is directly compositional from 'speed' (measure of how fast), 'of' (possession/relation), and 'light' (the physical phenomenon), so a learner who knows the constituent words can readily infer the phrase. This literal noun phrase and its figurative extension ('extremely fast') follow a common cross-linguistic pattern, making it transparent to a B1 learner.
Etymology
Speed of light is often used as a vivid image because light moves so fast that things seem instant, so saying something happened 'at the speed of light' means it happened very, very quickly.
