Holograms are distinct from volumetric displays and Pepper's ghost illusions, showcasing 3D scenes with different perspectives.
Holograms come in various colors like red, green, and rainbow, with each part containing the entire image.
Light is composed of photons, behaving like waves, as demonstrated in the double slit experiment.
Light's wavelength determines its color, with longer wavelengths appearing red and shorter ones blue.
Phase differences in light waves affect their interference patterns, showcasing wave-like properties.
A Michelson interferometer experiment illustrates how phase differences in laser light create interference patterns.
Holograms capture 3D information by interfering two beams on a special film, encoding object details.
Single beam holograms simplify the process by mimicking two beams, using a specific setup.

To create a hologram, ensure to turn off fans, unplug the fridge and lights, and choose a quiet time for minimal disturbance.
No special equipment is needed, just basic precautions.
Start by warming up the laser, aligning the beam to cover both a glass plate and the object to be imaged.
Remove the glass plate, block the beam with black cardstock, insert the film plate, and wait for vibrations to settle.
Carefully remove the cardstock to expose the setup to the beam, ensuring stillness and silence for a few minutes.
The film allows for extended exposure without overexposure, with 3-5 minutes typically sufficient for a good image.
After exposure, block the beam again, remove the object, and view the hologram immediately without post-processing.
Reflection holograms involve a similar setup but with the object behind the film, requiring low-angle lighting for optimal viewing.
Different hologram recording media like photopolymer, silver halide, and photoresist offer varied results and methods, affecting the final hologram's appearance and utility.
