Do you mean—what is the difference between wide angle lens perspective and normal lens perspective? If not, I’m not sure what you mean.
If so, then:
A wide angle lens exaggerates the perspective distortion more than a normal lens, due to its wider field-of-view (FOV). The wide lens displays more of the same scene than a normal lens (narrower FOV) at the same lens-to-subject distance.
You can crop a wide lens image to represent what you would see if the scene were shot with a normal lens.
