Question

how do tractor beams work.?​

Answer 1

Answer:

The main challenge to building a tractor beam is pretty intuitive. When a stream of light hits an object, it tends to move in the direction that the light is. ... The researchers weren't only able to pull them with their tractor beam, they were actually able to manipulate the beam to only pull certain particles.

Answer 2

Answer:

The tractor beam would work in a new way. In this case, the light would pull an object toward the source of the beam even though the beam has the same intensity all along its length. ... But each photon is now moving at an angle relative to the beam. So when one bounces off an object, it exerts a smaller forward push.
