How is the final scene in the tomb an example of dramatic irony what do we know that romeo doesn't?

The final scene in the tomb is an example of dramatic irony because the audience knows that Juliet is not truly dead, but Romeo believes she is. We know that Juliet has taken a potion to fake her death, but Romeo is unaware of this and believes she has died. This creates tension and dramatic irony as the audience watches Romeo's tragic reaction unfold.
