Different types of transition effects 

1. Serene transitions provide  a calm, quiet effect to your slides. These effects add a smooth and professional look to your presentation. For example, the Fade and Wheel effect dissolves the content in your slide.
   
   
2. Flare transitions exhibit the slide like a movie or video. These effects are great for pictures and media files in your presentation.
   For example: 
   Fall effect: Current slide falls away, leaving the next slide in its place 
   Pivot effect: Next slide rotates in from the corner of the previous slide
   
   
3. Zing transitions provide a dynamic motion to reveal the upcoming slide.  
   For example:
   Cover: Layers each new slide over the previous slide as though they were pages in a book
   Cube: Rotates the current slide like a cube and presents the next slide on another face of the cube
