👤 whose
Whose work explained that light itself carries momentum?
Quick Answer
James Clerk Maxwell’s electromagnetic theory implied that light can exert pressure. Later experiments confirmed radiation pressure.
The Full Story
James Clerk Maxwell’s theory of electromagnetism showed that light is an electromagnetic wave and should carry momentum. That means light can exert pressure on objects, a prediction later confirmed experimentally. This idea became important in optics, astronomy, and technologies such as solar sails. It was another example of Maxwell’s theory predicting surprising physical effects.
