After knowing about it, question strike in our mind what is wave?
A wave is equal parts conversation and document. People can communicate and work together with richly formatted text, photos, videos, maps, and more.
A wave is shared. Any participant can reply anywhere in the message, edit the content and add participants at any point in the process. Then playback lets anyone rewind the wave to see who said what and when.
A wave is live. With live transmission as you type, participants on a wave can have faster conversations, see edits and interact with extensions in real-time.

Wavelet: A threaded conversation spawned within a wave. All participants on a wavelet have read/write access to content within the wavelet.
Blip: A single message that appears in a wavelet.
Participants: Each wave has a set of one or more participants who engage and interact in a wave. Participants are added to a wave by existing participants.
