- In physics, the difference between a real vs. virtual image is that a real image is formed when light converges at a point – like when you look at an apple on your desk – whereas a virtual image is formed from two divergent rays of light that never meet. In simple terms, a plane mirror creates an image of an object you cannot touch.

A mirror is a reflective surface that does not allow the passage of light and instead bounces it off, thus producing an image. The most common mirrors are flat and called plane mirrors. These mirrors are made by putting a thin layer of silver nitrate or aluminium behind a flat piece of glass.

There are two laws of reflection which are always followed by plane mirror and they are: The angle of incidence and the angle of reflection are always equal. The incident ray, the normal at the point, and the reflected ray, all lie on the same plane.

- As the size of the object and image are the same, the magnification (ratio of image size to the object size) is equal to +1.
- A plane mirror only forms virtual images of real objects. However, a plane mirror can form a real image of a virtual object when hit by a convergin...
- The angle of incidence will be 0°.
- The focal length of a plane mirror is infinite.
- For the plane mirror, the image distance is always equal to the object distance. So, the total distance between the man and his image will be (1+1)...
- Image Formation by Plane Mirror. The "object" could be any physical object or a source of light, but we often depict it as an upright arrow.
- Concave Mirror. The distance from the focal point to the mirror is called the focal length, f. We will not go into the details of the proof, but it can be shown using the small angle approximation that the focal length is equal to half the radius of curvature
- Principal Rays of a Concave Spherical Mirror. Using rays to determine the location, orientation, and the size of the image is known as ray tracing.
- Deriving Equations for a Concave Spherical Mirror. Since we are using the small angle approximation (we assume that all distances are close to the optical axis), the mirror can be approximated as flat where light is reflected, as shown by the bold vertical line.
Physics. Optics. Concave Convex Mirrors. Concave Mirrors and Convex Mirrors. A mirror is a surface that reflects almost all incident light. Mirrors come in two types: those with a flat surface, known as plane mirrors, and those with a curved surface, called spherical mirrors.

Apr 18, 2024 · Plane Mirror vs Spherical Mirror. A plane mirror is a flat mirror, meaning its surface is flat and reflects light without distorting the image. It reflects light according to the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
Jul 7, 2020 · A plane mirror is a mirror that has a flat reflecting surface without any inward or outward curve. A ray of light falling on a plane mirror is reflected at the same angle as the angle of incidence. As a result, the image formed by the mirror is sharp and undistorted.
Justification: For plane mirrors, the reflected image (a virtual image) and object are along the same line, perpendicular to the reflective surface. The image and object are equidistant from the mirror. If you are 3 m in front of the mirror, your reflected image will be located 3 m behind the mirror. Thus, the distance between you and the image
