The mirror used for shaving is

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.
