Is it possible to attract light
According to special relativity, a photon can never be at rest. Something that might be thought of as a 'trap' for a photon is an optical cavity. Sign up to join this community.

Light is made of particles called photons, bundles of the electromagnetic field that carry a specific amount of energy. With sufficiently sensitive experiments, you can count photons or even perform measurements on a single one. Researchers have even frozen light temporarily. The photon model was one of the first triumphs of quantum physics; later work showed that electrons and other particles of matter also have wave-like properties.
However, the short wavelengths of X-rays and ultraviolet light are suited to showing such small structure. With methods to see these high-energy types of light, scientists get a glimpse of the atomic world. Photons carry the electromagnetic force, one of the four fundamental forces along with the weak force, the strong force, and gravity.
As an electron moves through space, other charged particles feel it thanks to electrical attraction or repulsion. Because the effect is limited by the speed of light, other particles actually react to where the electron was rather than where it actually is. Quantum physics explains this by describing empty space as a seething soup of virtual particles.
Electrons kick up virtual photons, which travel at the speed of light and hit other particles, exchanging energy and momentum. Unlike matter, all sorts of things can make or destroy photons. An electron moving in a strong magnetic field will generate photons just from its acceleration. Similarly, when a photon of the right wavelength strikes an atom, it disappears and imparts all its energy to kicking the electron into a new energy level.
