What is transparencys?

Transparencies are thin sheets of transparent material, usually made of plastic or glass, used for displaying images or text on an overhead projector or other light source. They are often used in classrooms, conferences, and presentations to display information to a large group of people. The material used for transparencies is typically clear or frosted, allowing light to pass through, and can be printed on or written on with a marker. Transparencies can also be used for creative applications, such as layering multiple images or creating unique lighting effects. With advancements in technology, many presentations are now done digitally, but transparencies are still useful in situations where a physical, interactive display is desired.
