The minimum height of a plane mirror (B) to see the full image of a person should be half of the person’s height. This placement allows the mirror to reflect the entire body from head to toe without any part of the person being obscured or cut off. When a plane mirror is positioned at this height, the reflected image appears to be the same size and orientation as the actual person standing in front of it. This principle is based on the geometry of reflection, where the angle of incidence equals the angle of reflection, ensuring that the entire visual field of the person can be observed in the mirror. Therefore, for optimal viewing and to see a complete reflection of oneself or others in a plane mirror, positioning it at a height equal to half of the person’s height is recommended, providing an accurate representation without any distortion or missing parts.
The image formed on the retina of the human eye is a real and inverted image (A). When light enters the eye through the cornea and lens, it refracts and converges to form a focused image on the retina, which is located at the back of the eyeball.

The image formed on the retina of the human eye is a real and inverted image (A). When light enters the eye through the cornea and lens, it refracts and converges to form a focused image on the retina, which is located at the back of the eyeball. This image is inverted, meaning that the top-to-bottom and left-to-right orientations of the object are reversed on the retina compared to the actual object. Despite being inverted, this image is real because it can be captured and detected by the photoreceptor cells (rods and cones) in the retina. These cells convert light energy into electrical signals, which are then transmitted via the optic nerve to the brain for processing and interpretation. The brain reconstructs the visual information received from both eyes into a coherent, upright perception of the external world, allowing humans to perceive their surroundings accurately. Thus, the human eye forms a real and inverted image on the retina, crucial for visual perception and interpretation.

A convex mirror (D) is preferred to see the traffic behind while driving. Convex mirrors have an outward-curved reflective surface, which diverges light rays and provides a wider field of view compared to plane or concave mirrors. This wider field of view is crucial for drivers to monitor the traffic behind them and check for approaching vehicles in adjacent lanes. Convex mirrors help reduce blind spots by displaying a larger area, although objects may appear smaller due to the mirror’s shape. This characteristic ensures that the driver can maintain awareness of surrounding vehicles and make safer lane changes or maneuvers. The use of convex mirrors in vehicle side mirrors and rearview mirrors is therefore standard practice, enhancing overall driving safety by improving visibility and reducing the risk of collisions from unseen vehicles. Thus, the convex mirror is optimal for effectively monitoring traffic behind the vehicle while driving.

The mirror used for shaving is a plane mirror (C). Plane mirrors have a flat, reflective surface that reflects light without distorting the image. When you look into a plane mirror, you see a virtual image that appears behind the mirror, at the same distance as the object’s actual distance from the mirror. This virtual image is upright and of the same size as the object, making plane mirrors ideal for tasks like shaving where an accurate reflection is necessary. Unlike concave or convex mirrors, which distort the image to varying degrees, plane mirrors provide a true reflection with no magnification or reduction in size. This characteristic ensures that when using a plane mirror for shaving or other personal grooming tasks, you see a clear and accurate representation of your face, allowing for precise and effective grooming. Thus, the simplicity and accuracy of plane mirrors make them indispensable in everyday applications where precise reflection is essential.
Concave mirrors (C) are used in the headlights of vehicles. These mirrors have a reflective surface that curves inward, similar to the inside of a sphere.

Concave mirrors (C) are used in the headlights of vehicles. These mirrors have a reflective surface that curves inward, similar to the inside of a sphere. When a light source is placed at the focal point of a concave mirror, the mirror reflects the light rays into a parallel beam. This property is essential for vehicle headlights, as it enables the light to be directed forward in a concentrated and focused manner, providing better illumination of the road ahead. The use of concave mirrors ensures that the light is not scattered in all directions, which enhances visibility for the driver and improves safety during nighttime driving. By focusing the light into a powerful, straight beam, concave mirrors help drivers see further distances and identify obstacles or hazards on the road more effectively.
