Animation showing a light source firing photons at a plane mirror. The photons are reflected in a way analogous to balls bouncing from a surface (it doesn't really happen this way). Although photons are massless, they do carry energy at the speed of light and this gives them momentum.
Varying Prism1970-01-01T00:00:00+00:00Animation of monochromatic (single colour) light beams passing through a triangular prism whose shape varies with time. As the prism widens at its base so the rays are bent (refracted) more. Prisms have many uses in optical devices.PT3S//d3e1m60ptf1oym.cloudfront.net/2b2fbca9-abac-490e-b213-bfba00d265de/physics-anim-prism-rays-FHD-Russell-Kightley_xlarge.jpghttps://www.scientific.pictures/-/galleries/animations/-/medias/2b2fbca9-abac-490e-b213-bfba00d265de/pricehttps://www.scientific.pictures/-/galleries/animations/-/medias/2b2fbca9-abac-490e-b213-bfba00d265de/price

Photon Space Drive1970-01-01T00:00:00+00:00A laser (red box mounted on grey support) firing photons (purple) at a space craft to accelerate it. The photons are reflected from the craft's giant reflector. As the photons bounce back, they transfer momentum to the space ship, which speeds up.
