Best Answer

A hologram captures the interference pattern between two or more beams of coherent light (i.e. laser light). One beam is shone directly on the recording medium and acts as a reference to the light scattered from the illuminated scene.

A hologram is created by splitting a laser beam into two parts: the object beam and the reference beam. The object beam is reflected off the object onto a photosensitive material, where it interferes with the reference beam to create an interference pattern. When illuminated with light, this pattern recreates a 3D image of the object that appears to float in space.

How revolver works?

A revolver works by rotating a cylinder that holds multiple chambers, each loaded with a single cartridge. When the trigger is pulled, the hammer strikes the firing pin, igniting the primer in the cartridge, which fires the bullet. The cylinder then rotates, aligning a new chamber with the barrel, ready for the next shot.
