Image Formation by Convex and Cylindrical Mirror with Vertical Axis

Convex Mirror:

A convex mirror is a spherical mirror with the reflecting surface facing outwards. The center of curvature and the focus are behind the mirror. When an object is placed in front of a convex mirror, the image formed is virtual, erect, and smaller in size than the object.

Formation of Image by Convex Mirror:

- The rays of light from the object fall on the convex mirror.
- The rays reflect from the mirror and diverge.
- The image formed is virtual, erect, and smaller in size.
- The image is formed behind the mirror.

Cylindrical Mirror with Vertical Axis:

A cylindrical mirror is a mirror with a curved surface in one direction and a flat surface in the other direction. The axis of curvature is perpendicular to the cylindrical surface. When an object is placed in front of a cylindrical mirror with a vertical axis, the image formed is virtual, erect, and of the same size as the object.

Formation of Image by Cylindrical Mirror with Vertical Axis:

- The rays of light from the object fall on the cylindrical mirror.
- The rays reflect from the mirror and converge.
- The image formed is virtual, erect, and of the same size as the object.
- The image is formed at a distance equal to the distance between the object and the mirror.

Conclusion:

In conclusion, convex and cylindrical mirrors with vertical axes form virtual, erect, and either smaller or same-sized images depending on the type of mirror used. Convex mirrors form smaller images while cylindrical mirrors form same-sized images. It is important to note that these images are virtual and cannot be projected onto a screen.
