what is used to generate interference patterns in order to produce a hologram?\nshadows\nspectrometers\nlaser…

Brief Explanations:

Lasers are coherent light sources. In holography, a laser beam is split into two - a reference beam and an object beam. These two beams interfere with each other to create the interference patterns that are recorded on a photosensitive medium to form a hologram. Shadows, spectrometers, and prisms are not used for generating the interference patterns in hologram production.
