What is the most basic difference in the recording of reflection holograms and transmission holograms?

When a transmission hologram is broken into many pieces, each piece can reconstruct the image of an entire view of the object. Why?

When a reflection hologram is broken into many pieces, each piece cannot reconstruct the image of an entire view of the object. Why?

It is generally not possible to use commonly available photographic film to record holograms. Design a very particular hologram that can be made using these films.

What type of hologram, even if it is thinner than a wavelength of light, can record and reproduce a completely three-dimensional image? Explain.

Can holograms be made using one laser for the reference beam and another laser for the object beam? Why?

If you have to make a hologram using low-power diode lasers near a location that has trains going by all the time, what type of hologram should you try to make to optimize your chance of success?

Why can we use the sun to reconstruct the image of a reflection hologram but not of a transmission hologram?

Dennis Gabor discovered holography in 1947 before the laser was invented. How do you think he made the first hologram?

Explain how a reflection hologram selects the color from the light used to illuminate it.

You have made a reflection hologram using red laser light. Why is the image generally not red, but yellowish or greenish?

How is it possible to make a hologram with more than one scene that can be viewed one at a time through the full aperture of the hologram?

Why do we bleach the holograms after development?

Explain how a double-exposure hologram of an object that changes microscopically between exposures reveals the nature of the change.

When making holograms, we try to equalize the optical paths traveled by the reference and object beams. Why? Under what condition is this procedure not necessary?
