Unlike concave mirrors, convex mirrors always produce images that have these characteristics: (1) located behind the convex mirror (2) a virtual image (3). The center of curvature is the point at the center of the sphere and describes how big the sphere is. Spherical mirrors can be either concave or convex. This section will cover spherical mirrors. A virtual image is right side up (upright). Instead, you “see” the image because your eye projects light rays backward. A virtual image occurs when light rays do not actually meet at the image. A real image occurs when light rays actually intersect at the image, and is inverted, or upside down. An image formed by reflection may be real or virtual. The object is the source of the incident rays, and the image is formed by the reflected rays. This image that appears to be behind the mirror is called the image. When you place an object in front of a mirror, you see the same object in the mirror. Mirrors are made by putting a thin layer of silver nitrate or aluminium behind a flat piece of glass. If the light ray hit the object at a 30 degree angle, it will be reflected back at a 30 degree angle.Ī mirror is a reflective surface that light does not pass through, but bounces off of and this produces an image. When this happens, we say the ray hit the mirror normally. If, for example, a light ray leaves the top of an object travelling parallel to the principal axis, it will hit the mirror at a 0 degree angle, and be reflected back at 0 degrees. The angle in which a light ray hits the mirror is the same angle in which it will be reflected back. Continue for other extreme points on the object (i.e.Draw the incident ray for light traveling from the corresponding point on the object to the mirror, such that the law of reflection is obeyed.Pick one point on the image and draw the reflected ray that travels to the eye as it sees this point.Place a dot at the point the eye is located.The image size is also the same as the object size. ![]()
