Convex mirrors, also known as diverging mirrors, are curved mirrors where the reflective surface bulges outwards. When an object is placed in front of a convex mirror at a distance of 10 cm, several unique optical properties come into play, leading to specific outcomes.

Understanding Convex Mirrors

Before discussing what happens when an object is placed at a distance of 10 cm from a convex mirror, it's essential to understand some key characteristics of convex mirrors.

  1. Diverging Light: Convex mirrors are designed to diverge light rays that strike their surface. This divergence results in the reflected rays spreading out upon reflection.

  2. Virtual Image Formation: Convex mirrors always form virtual images. Virtual images are formed where the light rays appear to diverge from, rather than physically converging at a real point.

  3. Reduced Size: Objects appear smaller in convex mirrors compared to their actual size. This reduction in size is a result of the spread-out nature of the reflected rays.

What Happens at a Distance of 10 cm?

1. Virtual Image Formation

When an object is placed 10 cm away from a convex mirror, the reflection process begins. The light rays from the object strike the mirror surface and diverge upon reflection. This divergence causes the brain to interpret the rays as if they are coming from behind the mirror surface. Thus, a virtual image of the object is formed behind the mirror.

2. Size of the Virtual Image

Due to the diverging nature of the light rays in a convex mirror, the virtual image produced is always smaller than the actual object. The degree of size reduction depends on the radius of curvature of the mirror and the distance of the object from the mirror surface.

3. Loss of Specific Details

As the object moves closer to the convex mirror, the virtual image produced loses some specific details. The image may appear blurred or distorted, especially if the object is very close to the mirror.

4. Wide Field of View

Convex mirrors have a wide field of view, making them useful in situations where a broad area needs to be observed, such as in side-view mirrors in vehicles. Placing an object very close to the mirror can enhance this panoramic view.

Factors Influencing Image Formation in Convex Mirrors

  1. Radius of Curvature: The curvature of the mirror surface plays a crucial role in determining how the image is formed.

  2. Distance of Object: The distance between the object and the mirror affects the size and position of the virtual image.

  3. Type of Mirror: Convex mirrors always produce virtual images, as opposed to concave mirrors that can form both virtual and real images, depending on the object's position.

Frequently Asked Questions (FAQs)

1. Can a convex mirror form a real image?

No, convex mirrors always form virtual images. Real images are formed by concave mirrors when the object is placed beyond the mirror's focal point.

2. Why does the size of the image formed by a convex mirror appear smaller?

The size of the image appears smaller due to the diverging nature of light rays from convex mirrors, leading to a reduction in the perceived size of the object.

3. Is the image formed by a convex mirror always erect?

Yes, the virtual image formed by a convex mirror is always erect, meaning it is oriented in the same way as the actual object.

4. What is the focal length of a convex mirror?

The focal length of a convex mirror is considered negative and is half the radius of curvature of the mirror.

5. How does the distance of the object affect the nature of the virtual image formed by a convex mirror?

As the object moves closer to the convex mirror, the virtual image's size decreases and may become more distorted, as the mirror surface cannot accurately reflect rays from very close objects.

6. Where are convex mirrors commonly used in everyday life?

Convex mirrors are widely used in security mirrors, automobile side-view mirrors, decorative mirrors, and store surveillance mirrors due to their ability to provide a wide field of view.

In conclusion, placing an object 10 cm away from a convex mirror results in the formation of a smaller, virtual image behind the mirror surface. Understanding the unique properties of convex mirrors and how they interact with light rays is crucial in comprehending image formation in such optical devices.
