Convex Mirrors
A convex mirror is a curved mirror in which the reflective surface bulges outwards. It is also known as a diverging mirror because parallel rays of light diverge after striking the mirror. Convex mirrors are commonly used in everyday objects such as car side-view mirrors, security mirrors, and makeup mirrors.
Characteristics of Convex Mirrors:
- Curved Outward: The reflective surface of a convex mirror curves outwards, creating a wider field of view.
- Diverging Light: When parallel rays of light strike a convex mirror, they diverge or spread out.
- Virtual Image: Convex mirrors always produce virtual images that are upright and smaller than the object being reflected.
- Wide Field of View: Due to their outward curvature, convex mirrors provide a wider field of view compared to flat mirrors.
Uses of Convex Mirrors:
Convex mirrors have various practical applications due to their unique optical properties:
- Car Side-View Mirrors: They provide a wider field of view for drivers, making it easier to see objects and vehicles behind the car.
- Security Mirrors: Used in stores, parking lots, and other public places to provide a wide-angle view for security and surveillance purposes.
- Decorative and Makeup Mirrors: Convex mirrors are also used for decorative purposes and in makeup mirrors to provide a wider reflection.
Study Tips:
When studying convex mirrors, consider the following tips:
- Understand the concept of virtual images and how they are formed by convex mirrors.
- Practice drawing ray diagrams to show the formation of images by convex mirrors.
- Learn about the differences between convex and concave mirrors, including their focal points and magnification properties.
- Explore real-world examples of convex mirrors and their applications in daily life.
By understanding the characteristics and uses of convex mirrors, you can appreciate the role of these optical devices in various practical applications and everyday experiences.

Chemistry: Students will use scientific skills and processes to explain the composition, structure, and interactions of matter in order to support the predictability of structure and energy transformations.
Structure of Matter: Cite evidence to support the fact that all matter is made up of atoms, which are far too small to see directly through a microscope.
Recognize and describe that the atoms of each element are alike but different from atoms of other elements.
Recognize and describe that different arrangements of atoms into groups compose all substances.
Provide examples to illustrate that elements are substances that do not breakdown into smaller parts during normal investigations involving heating, exposure to electric current or reactions with acids.
Cite evidence to explain that all living and non-living things can be broken down to a set of known elements.
