Final answer:
The transitional device where one image is pushed aside by another is known as a wipe transition, commonly seen in film and other storytelling mediums to create a seamless narrative flow.
Step-by-step explanation:
The transitional device where one image appears to be pushed aside by the next is called transition. This technique is used to indicate a shift from one key idea or image to another. For example, in Masaccio's fresco painting on the wall of the Brancacci chapel, he uses transitions to make the drama unfold.
In the context of visual arts and film, the transitional device where one image appears to be pushed aside by the next is known as a wipe transition. This technique can effectively move the narrative from one scene to another by literally having the new image push the old one off the screen. This type of transition can be seen in various media forms, such as comic books, films, and in certain kinds of animations.
In practical applications within the theater, for instance, transitions might require technical adjustments on stage, such as changes to the set or costumes. In filmmaking, transitional devices like the wipe create a seamless flow in storytelling without breaking the viewer's immersion, much like swift scene changes in theater aim to keep the audience connected to the narrative.
The concept of transition is crucial in storytelling across mediums, and using transitions like the wipe helps to maintain the momentum and clarity as the story moves from one key idea or scene to the next.
