(a) What are the characteristics of an image formed by a plane mirror? (b) Write few uses of plane mirror.

A plane mirror is a flat, smooth surface that reflects light at the same angle it receives it, forming a virtual image. The characteristics of this image are: 1. The image is virtual: This means that the image formed by a plane mirror appears behind the mirror, and it cannot be obtained on a screen. 2. The image is upright: The image appears in the same orientation as the object. 3. The image is laterally inverted: The left and right sides of the image are reversed compared to the object. 4. Same size as the object: The image is magnified to the same size as the object. 5. Equal distance from the mirror: The image is at an equal distance behind the mirror as the object is in front of the mirror. Now, let's move on to the uses of plane mirrors.

Plane mirrors can be found in various aspects of our daily lives due to their unique optical properties and practical applications. Some uses of plane mirrors are: 1. Personal grooming mirrors: Plane mirrors are commonly used in bathrooms, bedrooms, and dressing rooms for grooming purposes, such as hairstyling, applying makeup, and shaving. 2. Interior design: Plane mirrors are used to create the illusion of more space and depth in a room, making it appear bigger. 3. Periscopes: A periscope consists of two plane mirrors inclined at a 45-degree angle to allow the user to see above, around, or through obstacles. 4. Reflecting telescopes: Plane mirrors are used in reflecting telescopes as primary mirrors to collect light from distant objects and focus it to form an image. 5. Kaleidoscopes: A kaleidoscope is an optical instrument that uses multiple plane mirrors arranged in various angles to create beautiful symmetrical patterns from light reflected inside the instrument. 6. Retail stores: Plane mirrors are used in fitting rooms to allow customers to try on clothes and see how they look, assisting them in their decision-making process.
