Are Rainbows Holograms?
- peter_d_sherman 7y ago>"A rainbow has many properties associated with holograms. Is the effect of rainbows in clouds essentially holographic? [...] o Like a hologram, a rainbow is composed of countless nearly identical sources of coherent light, reflected and refracted off water droplets. o Like a hologram, a wavefront emerges from the cloud of rain droplets, but what you see are not the individual droplets but a whole image which depends on your relationship to the light source and the cloud. When you move, the rainbow moves. o Like a hologram, a given point in the cloud (or a given point on the holographic film) doesn't correspond to a particular part of the rainbow (or the object being holographed). For instance, depending on your perspective, a given region in space may appear red or violet."
