Who is credited with inventing the theory of holography in 1947, Albert Einstein , Dennis Gabor, Nikola Tesla, Thomas Edison, True or False: A "holograph" is just another word for a 3D laser projection., True, False, Which technology's invention in 1960 was crucial for making high-quality, practical 3D holograms?, The digital camera , The laser, The electron microscope, The fiber optic cable , Holograms are created by splitting a single laser beam into an object beam and a reference beam., True, False, High-end, professional holographic setups for corporate events are highly affordable, costing under ₹10,000., True , False, Which type of hologram requires light to pass through the film from behind, Transmission hologram, A complete blackout shield that blocks all light, A mirror that bounces light directly backward, A solid brick wall that reflects nothing, If you break a real hologram film into four pieces, what happens when you shine a laser through one piece, The image flips upside down and turns black and white, You see only one-quarter of the original image, The image disappears completely into a blurry smudge, You see the entire original image, just from a smaller viewing angle., When computer software generates a digital hologram, what math process does it use to calculate how light moves, Pixel counting algorithms, Fourier transforms and diffraction formulas, Basic subtraction matrices, Standard video compression codecs, What material is used to mass-produce the cheap, shiny holographic security stickers found on credit cards, Thick silver halide glass plates, Photoresist plastic that deforms physically under laser light, Layers of translucent animal gelatin, Magnetic tape strips coated in metallic paint, Why is the "Pepper's Ghost" stage illusion not considered a true hologram?, It relies on a flat 2D reflection off a piece of glass or foil, rather than encoding actual 3D light waves, It can only project historical figures who are no longer alive, It requires actors to wear special tracking glasses to see the imag, It only works if the room is completely pitched black..
