Macbeth learns about Lady death after the audience does. What literary technique does Shakespeare use by doing this?

Shakespeare uses dramatic irony by having the audience learn of Lady Macbeth's death before Macbeth does. Dramatic irony is a literary device in which the reader or audience knows more about a situation than the characters in the story. This creates a sense of suspense and anticipation, and it can also make the characters' actions seem more tragic or foolish. In the case of Macbeth, the audience knows that Lady Macbeth is dead, but Macbeth does not. This makes his grief and confusion all the more poignant.
