The correct answer is: C. A special effect used to introduce a slide in a slide show.
A slide transition is a special effect that is used to introduce a slide in a slide show. It can be used to create a more visually appealing presentation, or to help the audience follow the flow of the presentation. There are many different types of slide transitions available, and the best type to use will depend on the specific presentation.
Some common types of slide transitions include:
- Fade: The slide fades in from black.
- Wipe: The slide appears to be wiped onto the screen from one side or the other.
- Dissolve: The slide dissolves into the next slide.
- Push: The slide appears to be pushed off the screen by the next slide.
- Checkerboard: The slide appears to be made up of small squares that are replaced one by one by the next slide.
- Random: The slide transition is chosen at random from a list of available transitions.
Slide transitions can be applied to individual slides or to all slides in a presentation. They can also be customized to change the speed, direction, and other effects.
Here is a brief explanation of each of the incorrect options:
- Overheads: Overheads are a type of presentation that uses transparencies to project images onto a screen. They are no longer commonly used, as they have been replaced by more modern technologies such as PowerPoint presentations.
- Letters: Letters are a type of character that is used to represent words and sentences. They are not typically used in slide transitions.
- The way one slide looks: The way one slide looks is determined by the content of the slide, the design of the slide, and the slide layout. It is not typically referred to as a slide transition.
