For notational inconvenience, we usually drop the matrix and regard the inner product as a scalar, i. Under reflection, the shape and size of an image is exactly the same as the We saw above the transformation matrix for reflection in the line y = x (which by definition goes through the origin at an angle of forty-five degrees). Introduction This is just a short primer to rotation around a major axis, basically for me. For example if objects are reflected in the two red lines (which are θ degrees apart) then the objects will be rotated by 2 * θ degrees. Rule 2: A ray of light going towards centre of curvature is reflected back along the same path. I thought about it this way. Login. If we know what the matrix does to the vectors (1,0) and (0,1), we've got the whole thing. Likewise, a Y matrix requires “shorts”, again ideal shorts are impossible A reflection is a transformation representing a flip of a figure.
