Momentum and energy from focused laser beams can be used in nuclear fusion. This is because
A) light cannot be melted, so its pressure can confine the reaction.
B) light is not magnetic.
C) light can also function as a moderator, like graphite or water in a uranium reactor.
D) the wavelength of light is small enough to penetrate each proton.

Question

Quizplus · Accepted Answer

Light's inability to melt allows its pressure to confine the nuclear fusion reaction, as it can exert force without undergoing physical changes that would compromise its ability to maintain the necessary conditions for fusion.
