Question
Mask the outer rays from the ray box so that you have only the two central rays. Direct the parallel rays at the circular mirror parallel to the axis of symmetry but displaced slightly sideways. Record the position of the focal point. Repeat the procedure, moving box to six different positions and recording the focal point, always keeping the rays parallel to the axis of symmetry. The fact that the mirror doesn't focus the rays to a single point is called an aberration. Do the focal points lie on a curve or a straight line? When four rays that are parallel to the axis of symmetry of the mirror are focused, do they really focus at one point?Explanation / Answer
4)The focal points lie on a straight line.
5)yes, if four rays that are parrallel to the axis of the circular mirror are focused, they do really focus at a single point called focal point of the mirror as it is a circular one
